Healin' Good♡Pretty Cure — Season 1

13-year-old Nodoka Hanadera and her family moved into the town of Sukoyaka in hopes that would give her a fresh start. Meanwhile in another world, Queen Teatine entrusted the care of her daughter Latte to Rabirin, Pegitan and Nyatoran to find people whose hearts resonate with their paws. While the Healing Animals were searching for their partners in the human world, Nodoka is relaxing in the city and meeting up with some new friends. Both parties suddenly witness a monster attack caused by a group named the Byogens with one of its generals, Daruizen, creating the said monster. As Latte was weakened, the Healing Animals engage them to no success while Nodoka decided to investigate deep in the forest until she found Rate in critical condition. Nodoka was about to take the dog to safety until the animals explain that the only way to cure its condition is to defeat the MegaByogen as they were created by infecting an elemental spirit. Nodoka's resolve to help resonated with Rabirin, allowing her to transform into a Pretty Cure of Legend: Cure Grace and defeat and purify the MegaByogen, making Latte healthy again.

After the incident in the park, Nodoka took Rate home and convinces her parents to keep her for a while, to which they hesitantly agree. At another world, the Byogens were aware about the appearance of Cure Grace and how it will ruin their plans on infecting the world. The next day, Nodoka goes to her first day at school, and the animals come with her in the hope of finding partners for Pegitan and Nyatoran. Nodoka discovers she is in the same class as Chiyu Sawaizumi and Hinata Hiramitsu, two girls she met the previous day. After school, Rate sensed another MegaByogen attack as she calls out and draws Rabirin and Pegitan back to her (Rabirin had broken up her partnership with Nodoka earlier in the day and left with Pegitan trying to follow her). Hoping to make up for her lost time, Nodoka wants to help protect the world as a Pretty Cure. Rabirin realizes she was wrong about Nodoka and the two reconcile. Nodoka transforms into Cure Grace and defeats the MegaByogen, freeing the Tree Spirit trapped in the monster.

Nodoka overhears her classmates taking about the recent monster attacks, but Rabirin implores her to keep her Pretty Cure identity a secret. Meanwhile, Nyatoran leaves Pegitan to look after Rate while he tries to find a partner, but Rate sneaks off leaving Pegitan to find her. However, another Byogen general, Shindoine, infects the water source in Chiyu's family Onsen at their inn. Nodoka transforms into Cure Grace in front of Chiyu and reveals her identity, but was overwhelmed by the MegaByogen. Chiyu asked Pegitan to lend her his powers to help Cure Grace as she can't last long in her fight. Her own resolve resonated with the penguin and allowed Chiyu to transform into Cure Fontaine. Together, they both defeated the MegaByogen and purify the Water Spirit trapped in it. Afterwards, Nodoka explains to Chiyu everything and entrusts her to look after Pegitan.

Nodoka calls Chiyu over to her house when it appears that Rate has become ill. As there doesn't appear to be a MegaByogen attack anywhere, Chiyu believes that they should take her to the local Veterinary Hospital run by Hinata's family. Meanwhile, Hinata was running late to her friend's outing to the mall when Nyatoran rushed to her to return her lipbalm. This causes her to affectionately thank the kitten until his sudden talking amuses her. Back at the Veterinary Hospital, Rate was treated by a vet there much to Nodoka's relief until Hinata came in and showed them Nyatoran, forcing Nodoka and Chiyu to drag her outside. Nodoka and Chiyu fear that Hinata was going to discover their secret, until Nyatoran played it cool and told her he's the world's first talking cat. As both learned that Hinata is indeed late to her friend's hangout to the mall, they all decided to go there. However, a third Byogen general, Guaiwaru, creates a MegaByogen to terrorize the area. As both Nodoka and Chiyu transform and prepare to attack, Hinata, having returned to the mall to find them, was ecstatic and amazed on what she is seeing. Nyatoran, impressed by Hinata's spirit, offers to be her partner and allows her to transform into Cure Sparkle. Cure Sparkle defeats the MegaByogen, purifying the Light spirit and healing Rate. Afterwards, Hinata apologizes to her friends for being late and both Nodoka and Chiyu followed her to make sure she never tells them their Pretty Cure identities.

Nodoka and Chiyu keep reminding Hinata to keep their Pretty Cure identities a secret, as she nearly lets it slip whenever her friends talk about the monster attacks. As they visit the town's aquarium, hilarity ensues when it appears that Chiyu and Hinata's personalities clash with each other. But then they notice that Pegitan was missing as he is running away from the aquarium staff who mistook him for one of the birds in captivity. While the trio search for him, things become more problematic when Shindoine creates a MegaByogen and accidentally captures Pegitan in the middle of the attack. Arriving at the location of the MegaByogen first, Chiyu and Hinata see Pegitan and decide to take him back. Nodoka arrives just as Shindoine releases Pegitan, and the three girls transform to battle the MegaByogen and defeat it. Chiyu reprimands Hinata for being reckless and putting herself in danger with Hinata apologizing as both girls reaffirm their friendship.

Nodoka introduces her new friends to her parents, both of whom are relieved that their daughter is getting along so well. Unfortunately, it means that Rate will be stuck at home alone for a few hours a day as Nokoka and her father also have school and work respectively. Rate becomes down-hearted over being alone, even when the Healing Animals come to keep her company until a sudden opening of the door allowed her to escape to the town. The Healing Animals are worried and decided to call their partners to find her. After the girls find Rate in a local delivery company, Rate explains to the girls that Nodoka's mom reminded her of her real mother, Teatine, and that she felt like a real mother taking care of her back in the Healing Garden. Chiyu asks the staff of the delivery company where Yasuko Hanadera, Nodoka's mother, is and learns she is working in a local Strawberry farm. In there, Daruizen created a MegaByogen that infects the farm while Daruizen knocks Yasuko unconscious. The Cures rush to the farm and fight it, managing to defeat the MegaByogen with Cure Grace purifying the Fruit spirit, who gives her a new elemental bottle.

Nodoka discovers that the editor of the school newspaper, Michio Masuko, is spying on her as he believes that she may be linked to the monster attacks happening in Sukoyaka. One day while walking in the forest, Nodoka spots Michio and attempts to run away from him, only to trip and injure herself. Michio discovers Guaiwaru summoning a MegaByogen. Michio confronts the MegaByogen, but it knocks him over and he loses his glasses. The Cures arrive and fight the MegaBjögen and purify the Rain spirit. Afterwards, Nodoka helps Michio, who apologizes for suspecting her.

Chiyu is in training for an upcoming track and field event. However, she suddenly loses the ability to perform the high jump at her usual standards. Pegitan becomes worried and after consulting his treatment books, comes to the conclusion that Chiyu has a case of the 'Yips'. On the day of the event, Daruizen creates a MegaByogen to disrupt the activities. The Cures fight the MegaByogen and defeat it. The freed Ice spirit gives a new elemental bottle to Chiyu, who also regains her confidence and manages to complete the high jump.

Hinata notices that Nodoka has a photo collection but it does not contain any recent photos of her. Nodoka explains that she doesn't have any photographs taken since before she was ill, causing Hinata to suddenly get an idea and drag Nodoka and Chiyu to the Mall. When Rate runs off, Hinata goes to retrieve her and discovers Shindoine has created a MegaByogen from a Gem Spirit to terrorize the Mall. Hinata transforms and tries to engage the MegaByogen on her own but is beaten back until Cure Grace and Cure Fontaine join the battle. The three Cures then proceed to defeat the MegaByogen. After purifying the Gem spirit, Hinata takes Nodoka and Chiyu back to the shop to finish having their picture taken.

The girls take a train ride to a museum, where Nodoka meets a sculptor who makes art from glass. However, they are shocked to discover that the Healing Animals and Rate have decided to come and join them, despite being asked to stay home. Unfortunately, Guaiwaru summons a MegaByogen to infect the museum forcing the three to transform and fight it. But a much bigger problem occurs as Rate sensed two more MegaByogens in two different areas, forcing the team to split up and take on the MegaByogens one by one. Cure Grace struggles to take on Guaiwaru's MegaByogen despite Rabirin pleading her to shift her focus on the others. As Grace goes down, the three Cures regroup and defeat the MegaByogen before moving on to the next. Before leaving, Cure Sparkle receives power from the purified Light Spirit.

The Cures race to the second MegaByogen, created by Shindoine to pollute a river, managing to purify it before Cure Fontaine receives power from the Water spirit. The final MegaByogen created by Daruizen is terrorizing a meadow of flowers. However, their encounter with it was unsuccessful as the MegaByogen's infection on the area was now too powerful for the Cures and overwhelms them. After the attack, Daruizen noticed that the MegaByogen created a dark seed that went somewhere. As they regroup, the trio was about to give up until the other earth elemental spirits rushed into the area where the MegaByogen is. The trio again transform and went back to fight against the more powerful MegaByogen. As all hope is about to be lost, Cure Grace encourages the Flower Spirit to not give up, which combines with the other spirit powers, causing the Miracle Healing Bottle to appear. The Cures perform Healing Oasis to defeat the MegaByogen and purify the Flower Spirit. However, the seed from the last MegaByogen goes unnoticed and infects a Nutria.

After their previous encounter with multiple MegaByogens, the Healing Animals decide to put the Pretty Cure through a boot camp to improve on their teamwork. Suddenly, a MegaByogen appears along with a new Byogen general named Batetemoda. The girls transform and attempt to fight the MegaByogen, only for Batetemoda to beat them back. Finally working together, the three Cures manage to defeat the MegaByogen and beat back Batetemoda, who reveals that he was made from the same seed from Daruizen's last MegaByogen before retreating. Nodoka and Chiyu agree that they will continue to work hard to prevent more generals from being created, but Hinata secretly begins to have doubts.

Hinata begins to consider quitting being a Pretty Cure, much to the dismay of her friends. While trying to explain her feelings, Rate senses a MegaByogen so the girls go looking for it. Despite Rate's directions, the girls are unable to find the MegaByogen but discover that everyone around town is suffering from static electricity building up, and assume it must be the MegaByogen. However Hinata begins to voice her doubts again, even when her sister becomes trapped in her Juice van, but Nodoka and Chiyu manage to encourage her to do her best. Suddenly the girls discover a drone which has been infected by the MegaByogen and realize it must be flying around town. Hinata manages to track the MegaByogen, along with Guaiwaru and Batetemoda, and the girls transform to fight it. With the help of Cure Fontaine's Ice bottle, the Cures are able to defeat the MegaByogen and free the Lightning Spirit using Healing Oasis. Afterwards, the Lightning Spirit gives Hinata a new elemental bottle, and Hinata resolves to do her best in the future.

Nodoka attends a doctor's appointment where she is happy to find out she has fully recovered from her previous illness. She is also excited to discover that Sukoyaka City is holding a festival. At the festival Nodoka meets up with Hinata and Chiyu and learns all about Sukoyaka city, most importantly the teamwork the citizens have with each other. However, Batetemoda creates a MegaByogen to disrupt the festival, but the girls transform and manage to defeat it with the help of Cure Sparkle's new Lightning Bottle. Afterwards, the Wind Spirit reveals to them that a girl who lived in Sukoyaka long ago became the first Pretty Cure after partnering up with Teatine and had the power to heal people through melody.

Rabirin and the other Animals come across a Daruma doll outside a Lavender Tea shop. Nyatoran openly scoffs the doll but Rabirin secretly likes it. Rabirin confides in Nodoka about the doll and Nodoka agrees to help her get one in a promotional event being held at the shop. However, when Rabirin finally gets the doll, Nyatoran finds out causing Rabirin to become embarrassed and throw it away. Nodoka becomes upset with Rabirin and the two have their first argument. The next day, both Nodoka and Rabirin still feel animosity towards each other, which complicates matters when Daruizen creates a MegaByogen and Nodoka and Rabirin find they cannot transform. Cure Fontaine and Cure Sparkle engage the MegaByogen while Rate forces Rabirin and Nodoka to talk. Rabirin apologizes to Nodoka for the way she acted and the two reconcile and transform to help the other Cures defeat the MegaByogen. Afterwards, the Leaf Spirit gives Nodoka and Rabirin a new elemental bottle.

After learning about the legend of the Eternal Tree, Nodoka, Chiyu and Hinata find the tree in order to make a vow of friendship under it. However they are shocked to discover that the tree was killed during a recent storm. They also meet an old man who tells them that there is no such thing as eternal friendship. The girls learn from the tree's spirit that the man's name is Tetsuya, and that he made the vow with his two friends Fumi and Hideo 50 years ago. The tree spirit asks the girls to find Tetsuya's friends and bring them together before the tree is cut down. Nodoka agrees and the girls manage to find Fumi and Hideo, only to discover the truth behind their separation. Unable to convince the three to come together, Nodoka, Chiyu and Hinata make the vow under the tree, before deciding to hold a farewell festival for the tree. On the day of the festival, Batetemoda creates a MegaByogen from the tree spirit, causing Tetsuya to try and defend it before being rescued by Fumi and Hideo. The girls transform and defeat the MegaByogen, afterwards Fumi, Hideo and Tetsuya renew their friendship before Fumi reveals that a new sprout has grown from the tree.

Chiyu offers to help out at her family's inn for the weekend, where she learns about the importance of good hospitality from her mother and grandmother. She also meets an English speaking family with a young daughter named Emily, who are staying at the inn. Chiyu takes the three sight-seeing, but notices Emily seems unhappy although she does show an interest in the local park. Chiyu learns from Emily that she will be moving to Japan but is worried about not having any friends, so Chiyu promises to take her to the park the next day. However, Shindoine creates a MegaByogen to infect the park, but the girls transform and manage to defeat it and the Rain spirit gives Chiyu a new elemental bottle. The next day, Chiyu takes Emily to the park with Nodoka and Hinata to play, where Emily is able to make friends before leaving with a smile.

On his way to Nodoka's, Nyatoran comes across an Aromatherapy shop and become infatuated with its owner, causing him to injure himself. The owner, Ms. Orie, takes him to Hinata's family clinic where Hinata identifies Nyatoran as her pet cat. Nyatoran admits to the others he likes Ms. Orie, which worries Rabirin thinking he might change his partner, but Hinata shows surprising encouragement to Nyatoran. In order to repay Ms. Orie for her kindness, the girls offer to help her with the shop. Nyatoran eventually decides to make Ms. Orie a gift to express his feelings. However Batetemoda creates a MegaByogen to infect the shop, so the girls transform to fight it. Cure Sparkle is injured defending Nyatoran's gift, but the two come to realise they have mutual feelings for each other and carry on fighting. The Cures manage to defeat the MegaByogen and rescue the Fire spirit, who gives Hinata a new elemental bottle. Afterwards, as Hinata is about to give Ms. Orie Nyatoran's gift, a man named Mr. Kusaka appears and reveals he and Ms. Orie are married. Downhearted, Nyatoran confesses he is happy that Ms. Orie is smiling again and Hinata comforts him, but suddenly to everyone's horror, Rate falls ill.

The girls take Rate to Hinata's family clinic, where Hinata's brother examines her and deduces she is suffering from a cold. He gives Rate some medicine to take and instructs Nodoka to give her plenty of rest. Everyone helps out to look after Rate, leading her to confess to Nodoka that she feels useless, to which Nodoka reassures her she isn't. However due to her illness, Rate is unable to sense when Batetemoda creates a MegaByogen and by the time the girls discover it, the monster has already managed to grow incredibly powerful. The girls transform but are easily overpowered. Rate, feeling it's all her fault, attempts to stop the MegaByogen on her own but it proves too much and she is captured by Batetemoda. Queen Teatine, sensing something is wrong, begs the Earth to save her daughter. Suddenly a mysterious new Cure appears and saves Rate and the other Cures, allowing them to purify the MegaByogen and save the Wind spirit. Afterwards, the new Cure uses a new elemental bottle to heal Rate (though the latter is still not fully healed from her cold), while the other Cures wonder who she is...

The girls ask the new Pretty Cure who she is, with the Healing Animals commenting she looks exactly like the original Pretty Cure from long ago. However, the new Pretty Cure tells them she was created from the power of the Earth and Queen Teatine's wish to protect Rate, and is not a human but more like a fairy. She also reveals she has no name, so the girls refer to her as Earth. Earth then proceeds to take Rate back to the Healing Garden in order to fulfil her duty of protecting Rate. However, the others proceed to try and convince her not to leave, with Nodoka asking her to listen to Rate's feelings. Meanwhile, Batetemoda makes a deal with King Byogen to become leader of the Byogen generals if he defeats the Pretty Cure. Batetemoda managed to obtain crystalised fragments from the previous MegaByogen but Guaiwaru confiscates all but one of them. Batetemoda then creates a MegaByogen from a Sun spirit and powers it up using his remaining crystal. The girls transform but struggle to defeat the powered up MegaByogen. Earth, having listened to Rate, uses her Elemental bottle to transform into Cure Earth and uses her Earth Windy Harp to perform Healing Hurricane to purify both the MegaByogen and Batetemoda, killing the latter for good. Afterwards, the girls decide to give Earth a proper name and name her Asumi Fuurin.

Nodoka decides to let Asumi stay with her so that she can be close to Rate, managing to convince her parents Asumi is Rate's owner who has traveled to Japan from abroad. Nodoka helps Asumi to understand Earth customs as she has only been alive for one day and finds everything new and strange. The next day Nodoka injures herself protecting Asumi; when Asumi asks her why she goes to so much trouble to help out, Nodoka tells her that her experiences from being ill changed her and she wanted to repay the kindness she was given. Meanwhile, Daruizen creates a MegaByogen from a Flower spirit, and Guaiwaru reveals it can be powered up using the crystals he took from Batetemoda's possession which they call Mega Parts. Daruizen then discovers they can harvest more parts from the powered up MegaByogen. The girls arrive and transform to defeat the MegaByogen, with Cure Earth protecting Cure Grace from Daruizen. After Cure Earth purifies the MegaByogen, Asumi tells Nodoka that she hopes her own experiences change her in the same way Nodoka's did.

Asumi begins to settle down into life on Earth, but things get complicated when she becomes overprotective of Rate, causing Rate to avoid her and Asumi to begin to fade. Chiyu takes Asumi to her family inn and discovers Asumi becomes solid again when she experiences things she likes. However, as Asumi has no real concept of such emotions, Chiyu tries to explain it to her. The next day, the girls go to watch Chiyu at a sports event, where Asumi notices Chiyu continuously attempting the high jump despite failing. Chiyu explains that she tries so hard because she likes it. Suddenly, Shindoine appears and creates a MegaByogen from a Water Spirit, then powers it up with a Mega Part Daruizen gave her before harvesting another from the monster. Nodoka, Chiyu and Hinata transform to fight while Asumi goes to find Rate. Asumi realised that she was overprotective of Rate because she likes her so much and promises to take Rate‘s feelings into consideration in the future. Asumi then transforms and defeats the MegaByogen.

Hinata buys lots of different clothes for Asumi and has her try them on in front of Nodoka and Chiyu. All three girls comment on how cute Asumi looks but Asumi asked what cute is, as it's another emotion she has yet to experience. Hinata attempts to explain it before she is called away to look after a new foster puppy at her family clinic. Hinata explains that the puppy is named Pochi-to who is very timid. In an attempt to get the puppy to open up, Hinata planned to take him to a dog park. Everyone accompanies her and Pochi-to to the park, where Hinata explains to Asumi of the difficulties of getting Pochi-to to trust her from the beginning. Asumi also witnesses how the other owners interact with their dogs and tries and fails to befriend Pochi-to. Suddenly, Guaiwaru appears and creates a MegaByogen from a Fruit Spirit and powers it up to gather more Mega Parts. The girls transform, however all but Cure Earth are overpowered by the MegaByogen. Pochi-to tries to defend Cure Sparkle, but luckily Cure Earth saves him before he is killed by the monster; she then purifies it. Afterwards Asumi reveals she has come to understand her new feelings after experiencing the dogs and their owners at the park, before finally making friends with Pochi-to.

Hinata shows the girls a magazine article about a Cafe in the next town and asks if they want to go. However, the article also shows a secluded lake nearby which gets Asumi's attention. Nodoka decides that should visit the lake as it's Asumi's first outing. At the lake the girls meet an arborist named Sakuya Itsuki, who tells them all about the work she does with nature, impressing Asumi. That night, Daruizen uses a Mega Part on a bird the girls rescued earlier to create a new general. The next day Rate senses the lake is in trouble and Asumi manages to create a portal to transport everyone back there. The girls find Sakuya unconscious and the new general, Nebusoku, infecting the lake and the surrounding forest. The girls transform and manage to use Nebusoku's fear of flying to defeat him, with Cure Earth purifying him.

Pegitan becomes scared after watching a TV drama, causing Chiyu to reasure him that there's nothing to worry about before telling him how cute he is. However, Pegitan feels insulted by the comment, as he wants to act brave for Chiyu, and runs away. While thinking about what to do, Pegitan is happened upon by a young girl named Riri, who takes Pegitan home. Pegitan tries to escape back to Chiyu but learns that Riri struggles with being alone, as she has just transferred schools and her mother works late. Pegitan tries to help out by following Riri to school, only to get caught by one of the other students. However, this gives Riri the courage to save Pegitan and some of the other students help her, becoming her friends. After school, Riri thanks Pegitan for his help, during which, Chiyu and the others turn up. Riri, not wanting to lose Pegitan, runs home with him before Chiyu can catch up with her. Unfortunately, Shindoine creates a MegaByogen from a Gem spirit, so Chiyu leaves Nodoka, Hinata and Asumi to engage the monster while she tries to get Pegitan back. Riri locks Pegitan in her room, but he escapes after telling her she doesn't need him and that she is already brave. Pegitan returns to Chiyu and she transforms into Cure Fontaine before joining the other Cures and purifying the MegaByogen. Afterwards, Chiyu takes Pegitan back to Riri's house so that he can continue to visit her.

Hinata turns up deliberately late to meet Nodoka and the others in order to scare them, but is shocked to learn that Asumi doesn't display surprise like the others. Later on Asumi finds Nodoka in her garden making a diary of a Morning Glory plant she is looking after, and decides to make a diary of Rate's development to show Queen Teatine. Asumi goes round asking everyone about how they become Pretty Cure but is surprised to find everyone is busy and being secretive. She also learns of a fireworks festival that evening and believes that everyone is avoiding her as they want to go to the festival without her. This causes Asumi to begin to fade but Nodoka arrives and leads her to a festival party just for her, revealing they were all planning to surprise her. Asumi is grateful for the gesture and watches the fireworks with her friends.

Nodoka's father takes her and Asumi to a Hot-Air Balloon race to watch the team from his former college compete. Asumi learns about the feeling of passion and both her and Rate decide to cheer for the team too. However, when the team loses the first race, Asumi learns about the feeling of frustration but vows to help them win the next race by predicting the wind direction. Everything goes well until the team are just about to finish, during which, Guaiwaru appears and creates a MegaByogen, powering it up with multiple Mega Parts. The MegaByogen proves too strong for the Cures but is shown to be vulnerable to the wind direction. Cure Earth uses this to trap the monster in a vortex before purifying it. Afterwards, the freed Air Spirit gives Asumi a new elemental bottle. Later while everyone enjoys pancakes supplied by Hinata, Nodoka hears a sound in the nearby forest and goes to investigate. She finds Daruizen about to use a Mega Part on a crow and transforms into Cure Grace to confront him. However, Daruizen gets an idea and uses the Mega Part on Cure Grace, knocking her unconscious.

After Daruizen infects Cure Grace, the other Cures arrive to rescue her, only to arrive too late. They take Nodoka back to her parents, who rush her to the hospital revealing that the illness she is suffering from seems similar to her previous one. The girls talk and wonder if Nodoka was infected by a Mega Part before and the Healing Animals reveal that the Byogen generals were created from MegaByogens which have evolved to the most advanced stage. The girls go to visit Nodoka at the hospital where they witness the MegaByogen being purged from Nodoka by the combined effort of both her and Rabirin. After chasing the MegaByogen down, they find Daruizen is waiting for it to evolve, and everyone is surprised when it turns into an almost exact duplicate of Daruizen, named Kedary. Kedary proves to be very strong and the Cures have a hard time fighting him until Cure Earth uses her new elemental bottle to trap him, allowing the other Cures to purify him using Healing Oasis, killing him for good. However, after the fight, Daruizen reveals to Cure Grace that he remembers how he came into being: he was born from Nodoka after she was infected by a MegaByogen seed causing her initial illness. Daruizen leaves Cure Grace struck dumb by the revelation, but afterwards she resolves to do something about him.

Asumi notices an odd change in Nodoka who begins running and eating more, and after discussing it with the Healing Animals they come to the conclusion that Nodoka is stressed after the revelations of her illness and is finding ways to relieve it. But Asumi and the Animals feel she is overdoing it so they decide to find a different way for her to relieve her stress. Meanwhile, Nodoka meets a classmate named Kotoe Kanemori, who is a member of the school band. It is revealed Kotoe was home recovering from a cold but has returned to school; however she appears to be overdoing her trumpet practice in an effort to catch up with everyone else. This causes her to be scolded by the band leader Yuto Sugawara, who tells her not to rush and that the success of the band does not solely lie on Kotoe's shoulders. After school, Nodoka, Chiyu and Hinata meet up with Asumi and the Animals, who reveal what they've been doing, causing Nodoka to become a little defensive. Suddenly, Guaiwaru appears and creates a MegaByogen and powers it up with multiple Mega Parts in an effort to strengthen it much further. The girls transform to fight it, but Cure Grace becomes too reckless and almost gets crushed by the monster before being saved by Cure Earth. Earth gets Grace to admit she felt responsible for being involved in Daruizen's creation, which is why she has been trying to get stronger. However, Earth reassures her it isn't her fault and that she can rely on the others for support. The girls manage to defeat and purify the MegaByogen, after which the purified Sound Spirit gives Asumi a new elemental bottle to heal Rate.

The girls spend the day at the Zoo, where they meet a boy named Kota, who offers to show them round. Kota turns out to be the son of Nodoka, Chiyu and Hinata's home room teacher Kyousei Maruyama, and the girls learn he had a fight with his friend Shuichi because they both have different opinions on lions and tigers. However, Kota learns from the girls that being different can be a good thing and make friendships stronger, and he manages to reconcile with Shuichi. Meanwhile, King Byogen praises Guaiwaru and Daruizen for their discoveries of Mega Parts, leaving Shindoine jealous. Daruizen goes to the Zoo and creates a MegaByogen from a Leaf Spirit in order to collect more parts. The girls transform to fight the MegaByogen and manage to purify it, but not before Daruizen successfully harvests more parts from it. However, Shindoine gets an idea to use a Mega Part on herself, making her much more powerful. She decides to test her new strength by using a NanoByogen particle to infect Kota, but Kyousei Maruyama steps in the way and is infected instead.

The Cures discover what Shindoine has done to Kyousei Maruyama, after Rate becomes ill again. Shindoine reveals how she evolved herself using a Mega Part and can now create GigaByogens from living beings. The Cures attempt to fight the GigaByogen but are easily defeated, so Shindoine leaves to show King Byogen her new powers. During the brief respite, Nodoka, Chiyu, Hinata and Asumi regroup and find Kota in the Zoo, with Kota visibly shaken having witnessed his father turn into a monster. However, Nodoka reassures Kota the Pretty Cure will save his father. When Rate senses the return of the GigaByogen, the girls rush off to face it, but despite their best efforts they are unable to purify the monster with Healing Oasis. Determined not to give up, Nodoka rallies the other Cures and they engage the GigaByogen again. Their determination causes the power of all their elemental bottles to combine and create a new bottle. Rate combines all of their powers into one, forming the Healin' Good Arrow. The Cures use their new items to perform Final Healin' Good Shower to purify the GigaByogen and rescue Kyousei Maruyama.

Nodoka and Hinata join some of their classmates for work experience at Chiyu's family inn. Also joining them is Asumi and Chiyu's little brother Toji, who hopes to become more like his sister. Chiyu instructs Toji and her friends on good hospitality, but Toji begins to struggle when his hard work and kindness cause him to get into troublesome situations, leading Chiyu to scold him. However Pegitan, who had secretly watched Toji, asks Asumi to encourage him, which Chiyu overhears. Suddenly Guaiwaru appears, having powered himself up using a Mega Part like Shindoine, and transforms one of the inn guests, Mr. Chikara, into a GigaByogen. The girls transform to fight it while everyone else evacuates the inn. However during the fight, Toji tries to rescue a puppy from the monster and nearly gets hurt but is saved by Cure Fontaine. Cure Fontaine uses her Ice bottle to subdue the GigaByogen, with help from Cure Earth, before all four Cures purify it using Final Healin' Good Shower. Afterwards, the puppy is revealed to be Mr. Chikara's, who thanks Toji for rescuing it. Chiyu also expresses how proud she is of her little brother.

King Byogen forces Daruizen to power up using Mega Parts; despite being reluctant to do so, Daruizen complies. Meanwhile, Nodoka is paid a visit by Dr. Hachisuka, who looked after her while she was sick. Nodoka introduces Dr. Hachisuka to her new friends and he is grateful that Nodoka is doing so well. At dinner, Dr. Hachisuka reveals he quit his job at the hospital after he failed to cure Nodoka. Nodoka becomes upset and asks Rabirin if she can reveal the existence of the Byogens, but Rabirin dissuades her. Dr. Hachisuka goes for a walk with Nodoka and explains he changed careers to become a researcher who studies new illnesses to find a cure, and that Nodoka's encouragement is the reason, making Nodoka feel better. The next day, Dr. Hachisuka leaves but not before he and Nodoka make a promise to see each other again. However, he comes across Daruizen who turns him into a GigaByogen. After Rate senses Dr. Hachisuka is in trouble, the girls transform and try to rescue him. During the fight Daruizen engages Cure Grace, asking her what benefit working for others gives, but Grace is able to push him back, before helping the others purify the GigaByogen. Afterwards Nodoka watches Dr. Hachisuka leave, reaffirming her promise to meet him again when she grows up and the Pretty Cures' resolve to protect the world against the Byogens.

At a national sports event, Chiyu takes first place in the High Jump, breaking the current record. This causes Chiyu to be asked to do an interview with the second place competitor, Tsubasa Takami. After the interview, Tsubasa asks Chiyu if she will be competing in the international event, but Chiyu declines. However this angers Tsubasa, who reveals her passion for the High Jump, and that she feels Chiyu isn't taking her talent seriously. Chiyu becomes upset and confides in the others, who all comfort her, telling her that she can do things her own way. The next day at school Chiyu attempts to break her High Jump record, and finds she was only able to do it because of Tsubasa. Chiyu runs off to find Tsubasa, only to learn from her school friends that she has already left to move abroad. Chiyu manages to track Tsubasa down at the sports arena, where she is saying goodbye, until Shindoine appears and turns her into a GigaByogen. Chiyu transforms into Cure Fontaine and battles Shindoine before helping the other Cures defeat and purify the GigaByogen. Afterwards, Chiyu tells Tsubasa she plans to go to the international sports event and hopes they can compete against each other again one day.

After Rabirin, Rate and Asumi watch a volleyball television show, the three decide to take the others out to play beach volleyball. As such, the Healing Animals and the four girls head to a deserted island on a beach volleyball camp. While the others have fun playing, Nodoka struggles to keep up with the other three girls. Meanwhile, Guaiwaru arrives on the other side of the same island and infects a Tree Spirit to create a MegaByogen which he immediately subjects to intense sports training. As a result, Rate does not fully detect the presence of the Byogens until the MegaByogen finally initiates its rampage. The girls transform to engage the MegaByogen but the monster proves to be a formidable foe, having been taught volleyball moves by Guaiwaru. Cure Grace, despite initially failing to pass the MegaByogen's attacks repeatedly, rallies the other Cures before successfully deflecting the monster's attack. All four Cures then work together to defeat the MegaByogen before Cure Grace purifies it and the Tree Spirit. After the battle, the girls all decide to play beach volleyball again another time.

At school, the girls receive the results of their last test; Nodoka is thrilled to have improved since last time, while Chiyu as usual aces it. Hinata however scores low and reveals she just can't get into studying as she is easily distracted. Suddenly, she realizes she was supposed to meet a friend and runs off. Hinata meets Eriko, who moved away when she was in Elementary School. Hinata begins telling Eriko about her new friends, but Eriko suddenly storms off. Hinata feels the they have grown apart and begins to worry about her friendship with Nodoka and Chiyu, so she decides to try and study harder. The girls offer to have a study sleepover to help Hinata, but Hinata still struggles to remain focused. However, Hinata receives a message from Eriko asking to meet up the following day. Hinata meets up with Eriko but they are interrupted by Shindoine and a MegaByogen. Eriko takes Hinata to safety leaving the other girls to fight the monster. While hiding, Eriko confesses to Hinata she became jealous when Hinata told her about her new friends but that she really wanted to see Hinata and tell her everything. The MegaByogen finds the two girls but they are rescued by Cure Grace. Cure Earth takes Eriko to safety so that Hinata can transform and help the others defeat the MegaByogen and purify the Tree Spirit. Afterwards, Hinata realizes her friendships will last and decides not to worry about losing her friends.

Asumi reveals she has gotten a part time job to Nodoka, while the Healing animals decide to have an Autumn adventure with Rate. The Animals go round town and participate in their own secret events such as sports and art. They also learn from the Elemental Spirits about all the different people in Sukoyaka who help care for the earth, such as a local farmer. The Animals soon realize that there will come a time when they are no longer needed and become upset at the prospect of leaving their human partners. Suddenly, Daruizen appears and taunts them before turning the farmer into a GigaByogen. Luckily, Rate manages to escape and warn the girls allowing them to reach the Animals in time and transform. While battling the GigaByogen, the Animals realize that they can't be selfish and pull all their strength to defeat it and rescue the farmer. Afterwards, the Animals vow to help create a world that they can visit without needing to heal it.

When Toji expresses his interest in becoming an Innkeeper so that Chiyu can pursue her dream of becoming a high jump champion, Chiyu begins to doubt what she really wants. Chiyu acts distracted the entire day, something her friends take note of, so Pegitan explains the situation to them. When Rate finds the banner Nodoka and Hinata made to cheer on Chiyu, Petigan gets an idea and goes to find her. But before Pegitan can explain, Shindoine creates a GigaByogen at the beach. Chiyu transforms in Cure Fontaine and battles the monster until the other Cures turn up. After a brief confrontation with Shindoine, Pegitan tells Chiyu she can pursue both her dreams, giving her the courage to overcome her doubts. Cure Fontaine helps the other Cures defeat the monster and afterwards, Chiyu tells her family her decision, which they support.

Hinata accidentally discovers the portal to the Byogen Kingdom, left open by Guaiwaru, and tells her friends. Fearing a trap, the girls discuss with their partners the prospect of using the portal to go and fight King Byogen. After a reluctant debate the group decides to go, before the portal closes. In the Byogen Kingdom they encounter King Byogen, who engages Cure Earth before creating Byogen monsters to fight the other Cures. Although the monsters and King Byogen prove too strong at first, their determination allows the Cures to overcome and purify them. Having apparently defeated King Byogen, the girls celebrate, only for their celebration to be interrupted when they are confronted by Guaiwaru, who thanks them for getting rid of King Byogen for him, before revealing the fight isn't over.

Guaiwaru reveals his plans and enhances himself using multiple Mega Parts, strengthening himself further and anointing himself king. The Cures attempt to engage Guaiwaru but he overpowers all of them, especially Cure Sparkle who feels guilty for falling into Guaiwaru's ploy and leading everyone else into trouble and de-transforms. Guaiwaru prepares to finish her off only for the Cures to cover their tracks and evade him. Hiding in a quiet location, the girls discuss any means to escape from the Byogen Kingdom. Hinata tearfully expresses her regrets to the others, blaming herself for her current failure and believing she still fails no matter how hard she tries. The others comfort her, stating she does not need to feel responsible for that failure while complementing on her strengths. Rate then senses a hole made by Hinata; taking that lead, everyone realises they can use it to make a portal back to their world. After transforming again, the four Cures execute Final Healin' Good Shower to make their own portal and successfully escape through it despite Daruizen's interference. Arriving back on Earth, they discover that most of Sukoyaka City has been infected by Guaiwaru while they were trapped in the Byogen Kingdom. Her morale renewed, Cure Sparkle resolves to purify the town with everything they have, to which the other Cures agree.

Having escaped the Byogen Kingdom, the Cures begin purifying the MegaByogens around Sukoyaka City. With only a GigaByogen left the Cures head to the forest park where the citizens of Sukoyaka have taken refuge to intercept the monster. Meanwhile, Daruizen informs Guaiwaru that the Pretty Cures have escaped and both leave to confront the Cures during the battle with the GigaByogen, where they are also joined by Shindoine, who surprisingly appears to accept Guaiwaru as the new Byogen King. The Byogens manage to overpower the Cures but before Guaiwaru can deal the final blow, Shindoine betrays him and he is absorbed by King Byogen, who thanks to Guaiwaru's power, regains his body. King Byogen reveals that the Cures only destroyed part of his body, and that he was aware of Guaiwaru's treachery, so he planned to use him to regain his power and body with Shindoine's help. King Byogen then powers up the GigaByogen and forces the Cures to fight it. The Cures manage to purify it but find that King Byogen and his generals have disappeared, despite having the advantage. Afterwards, Nodoka and the others return home where they are greeted by their worried parents, who are thankful they are alright. Back in the Byogen Kingdom, King Byogen reveals his plan to use the Cures as bait and attempts to absorb Daruizen into his body, but Daruizen flees to find Nodoka. A wounded Daruizen confronts Nodoka, pleading with her to let him hide in her body to recover but Nodoka runs away terrified.

Nodoka is still shaken by her last encounter with Daruizen which leaves her family and friends concerned for her when she starts acting distant. Meanwhile, King Byogen tasks Shindoine to search for Daruizen while Queen Teatine and her servants prepare to head to Earth. Rabirin approaches Nodoka later in the day and the latter confides in the Healing Animal of her guilt of abandoning Daruizen. Nodoka also explains that she does not want to go through her painful experience of falling ill again, even though it shaped her. Rabirin encourages Nodoka to release her true feelings. Following the encouragement, Nodoka decides not to help Daruizen to which Rabirin agrees, stating she was not responsible for Daruizen's need and was already doing her best, even in maintaining her own health. Just then, Rate falls ill due to Daruizen enhancing himself with multiple Mega Parts and attacking the town's lighthouse, forcing Nodoka and Asumi to assemble their friends. The four girls transform to engage an evolved Daruizen, during which, the TerraByogen viciously attacks Cure Grace while 'asking' her to help him again. However, Grace, having her resolve renewed, refuses him, finally standing up for herself. She proceeds to beat down Daruizen before her comrades join her to purify the Byogen general. However, Daruizen is not completely purified and is subsequently absorbed by King Byogen who further evolves himself into Neo King Byogen as a result. Despite the evil king's taunts, a fully motivated Cure Grace resolves to purify the king.

To the Cures' horror, Neo King Byogen uses his power to infect all of Sukoyaka City at once with the resulting infection also gradually spreading worldwide. Determined to restore the city by purifying the king, the Cures attempt to engage Neo King Byogen but discover he is protected by a barrier; he also effortlessly defeats them, causing them to lose their transformations. However, Queen Teatine arrives in time to help the Cures; using her powers along with her Healing Animal friends, she creates a barrier to contain Neo King Byogen and stop his infection temporarily, allowing the girls time to figure out how to defeat him. However, they are forced to flee when Shindoine attacks them, with Asumi using her wind powers to transport them outside Teatine's barrier. During their moment of respite, Asumi reveals she may have a way to counter Neo King Byogen's barrier: by using the Byogens' power along with their own, they should be able to pass through it. However in order to do so, Asumi must take in a Mega Part so she can use Byogen power. Despite initial protests, everyone agrees after seeing Asumi's resolve. Shindoine appears once again and the girls transform to fight her, hoping to get her remaining Mega Part, however Shindoine uses it to become stronger. After an arduous battle, the Cures manage to defeat Shindoine using Final Healin' Good Shower, restoring her to her original form, but Rate manages to tell them to use Healing Oasis to purify Shindoine further and allow Cure Earth to absorb her Byogen particle. Now with the ability to combat Neo King Byogen, the Cures prepare to face him.

The four Cures return to the forcefield's area to engage and purify Neo King Byogen. When they battle the king again, Asumi initiates her plan and her attack manages to break through the king's barrier. However, Neo King Byogen, having his full strength restored, breaks out of the Healing Animals' forcefield, absorbs the Cures, Queen Teatine, Rate and the three Healing Animals and uses all of his power to immediately infect the entire world. Inside the king, Nodoka and her friends are apparently defeated. Neo King Byogen taunts Nodoka again, but Nodoka resolves to keep fighting on to protect everyone from him, despite the insurmountable odds. Motivated by Nodoka's speech, the others trapped inside also resolve not to give up, as do the people of Sukoyaka City, the other Healing Animals and millions more people worldwide. Breaking free from the king, the four girls transform again to engage him once more. Despite Neo King Byogen's sheer power and relentless assaults, the four Cures manage to overpower him before purifying him with Final Healin' Good Shower, destroying the king once and for all. Following the battle, the townsfolk, having discovered the Cures' identities, agree among themselves to keep their discovery under wraps. Life goes on in Sukoyaka City with the people discreetly thanking the four girls, until Asumi and the Healing Animals announce to their friends of their departure from Earth. The Healing Garden residents leave their companions in a tearful farewell, but not before promising to remain friends.

Rabirin, Pegitan and Nyatoran reunite with their companions to take them to the Healing Garden for a visit. There, the three girls meet Asumi, Latte and Queen Teatine again; the queen thanks the girls for aiding them in protecting Earth against the Byogens. All three visitors befriend the other Garden residents, giving them some buns they brought along. However, they struggle to get along with a grumpy monkey resident who believes that humans are no better than the Byogens. As the four girls ponder over the monkey's words, a couple of MegaByogens spawn in, due to a wild NanoByogen which hid in the bun containers infecting the girls' buns. The girls transform to engage the MegaByogens but the monsters prove to be tough enemies with perfect cooperation among themselves. As the four Cures struggle to fight back, Rate summons a new Cure, Cure Summer, to the battle. With assistance from that new heroine, the four Cures manage to finally defeat the MegaByogen pack and purify the Fruit Spirit trapped in them. Afterwards, the three humans apologise for their carelessness but Queen Teatine assuages them, while Asumi reassures the monkey that humans can still fix the damages done to Earth. After leaving the Healing Garden, Nodoka, Chiyu and Hinata resolve to continue healing the world for their lifetime.
