On the first day at her new school, things don't go too well for Hana Nono as she cuts her bangs short and ends up late for school. Just then, time briefly stops and she hears a baby's voice. She follows it to the rooftop, where she meets two other students, Saaya Yakushiji and Homare Kagayaki. Later that night, a baby named Hugtan and a hamster named Hariham Harry suddenly fall from the sky into Hana's house before disappearing just as mysteriously. The next day, Charalit, a dark employee of the evil Criasu Corporation, uses the negative energy of the students to summon a monster known as an Oshimaida. Noticing Hugtan is in danger, Hana rushes to her aid and gains the power of the Pretty Cure, using the Mirai Crystal and PreHeart to transform into Cure Yell and defeat the Oshimaida.

While keeping her identity as a Pretty Cure a secret from her classmates, Hana hears from Harry about how the Cryase Corporation is aiming to steal the Mirai Crystals and rob the world of its future. After Hana helps her work on the school newspaper, Saaya comes over to Harry's newly established hideout to help Hana look after Hug-tan, revealing she had experienced the same time stop as she did. Just as Hana and Saaya start to become friends, Charalit summons another Oshimaida, prompting Hana to reveal her identity as a Precure to Saaya. With Hana struggling to fight on her own, Saaya's courage grants her her own Mirai Crystal, allowing her to transform into Cure Ange and help Hana defeat the Oshimaida.

When Hug-tan starts acting cranky, Harry gives the girls the Mirai Pad, which points them towards something that will settle her down. Arriving at a petting zoo, Hana and Saaya come across Homare before they are joined by Hana's mother Sumire, who takes them to a tower and helps lull Hug-tan to sleep. When asked about the whereabouts of Hug-tan's mother, Harry explains how only he and Hug-tan managed to use the White Mirai Crystal to escape from their world before it was frozen in time by the enemy. Just then, Charalit summons yet another Oshimaida to attack the tower, prompting Hana and Saaya into action. Although the Oshimaida inflates to massive size, Hana manages to power through and defeat it. Afterwards, as Hana's family offer to help Harry with looking after Hug-tan, Homare feels a sense of longing after seeing the Precure in battle.

While thinking about scouting Homare as the third PreCure, Hana comes across her taking care of a stray dog, which she rescued while experiencing a time stop herself. Noticing some kids getting bullied over the use of a basketball field, Homare challenges the bullies to a match, but freezes up before making a throw, after which Hana wins the game by luck. Afterwards, the girls learn that Homare was once a famous ice skater who injured her leg following a failed jump, the mental scars of which have remained with her even though her leg had since healed. Just then, Charalit targets Homare's teacher to summon another Oshimaida, leading Hana and Saaya to reveal their identities and transform. As the Cures fight against the Oshimaida, Homare's feelings of wanting to fly again brings birth to her own Mirai Crystal, but her trauma over her failed jump leads her to hesitate, resulting in her Mirai Crystal disappearing before she can catch it. Noticing the Oshimaida react to the teacher's regret over not being able to help Homare, Hana manages to defeat it and return him to normal, but Homare still remains downhearted.

Homare is asked to help Harry set up his new shop, Beauty Harry, helping it to have a successful launch. Still concerned about Homare, Hana and Saaya assure her that there are things she can do that they can't. Just then, Charalit kidnaps Homare and traps her on the side of a building, using her negative energy over being unable to clear the gap over to the next building to summon another Oshimaida. Despite her fear, Homare regains her determination, finally obtaining her Mirai Crystal and the ability to transform into Cure Etoile. Combining their strengths, the three Cures manage to defeat the Oshimaida before becoming good friends.

To celebrate getting the team together, Hana takes everyone to a home center owned by her father Shintarou. Learning that the florist Mari is short-handed due to her part-time staff being off with colds, Hana and the others decide to help out, using the Mirai Pad to change into florists. As Hana becomes racked by a sense of deja vu upon seeing Saaya carry flowers, Hug-tan is picked up by a young customer, prompting the girls to search around the store for her until Shintarou manages to catch her. Just then, another employee of the Cryase Corporation, Papple, targets Mari to summon a Plant Oshimaida, but the Cures quickly manage to defeat it. As Sumire offers to help the girls experience all kinds of jobs, she recognises Saaya as a child actress who starred in an old vegetable commercial.

Saaya feels anxious over taking part in an audition against another actress who was in the same commercial, especially when it is revealed her mother, Reira, is a famous actress. Noticing Saaya becoming nervous during her audition, Hana and Homare disguise themselves as air attendants stumbling into the wrong audition to ease Saaya's nerves. Just then, the third member of Cryase, Ruru, summons another Oshimaida, using the data she had gathered from the Cures' previous battles to predict their moves. However, Saaya's desire not to give up gives form to another Mirai Crystal, and she manages to turn her usual defensive abilities into an offensive one, allowing the Cures to defeat the Oshimaida. As Saaya ends up failing her audition, but is nonetheless grateful for having taking part and figuring out her feelings, a strange boy approaches Homare.

Henri Wakamiya, a top skater and Homare's childhood friend, comes to ask Homare to return with him to Moscow, feeling that staying in Japan is preventing her from returning to form. As Henri remains assertive, he stands at odds with Hana, claiming that he is the only who can save her. Looking to disprove that, Homare shows Henri how much she has managed to improve thanks to Hana and Saaya's support. As Papple uses the negative energy of people stuck in traffic to summon another Oshimaida, Homare gains a new Mirai Crystal and manages to defeat it. Henri, who has deduced Homare's identity, decides to respect Homare's wishes and transfers into her school. Meanwhile, Hana comes across a peculiar man carrying a book with him.

While taking part in a hiking trip, the girls come across Emiru Aisaki, the classmate of Hana's sister Kotori, who is very cautious about the dangers of hiking to the point of bewildering her classmates. When a monkey runs off with Hana's tambourine, she and Emiru become separated from their group and wind up at the bottom of a pit. As Emiru laments causing trouble for everyone, Hana praises her for always striving to help everyone, and the two become friends. After reuniting with each other, the Cures fight against a Kappa Oshimaida created by Papple.

Using the Mirai Pad to help out at a food fair, Saaya and Homare become waitresses while Hana alone gets stuck in a different outfit helping out at a takoyaki stand. As the other two excel at their jobs, Hana becomes downhearted, feeling that she isn't able to do anything worthwhile. While trying to help draw customers to the takoyaki stand, Hana's reaction to trying one of the takoyaki draws laughs from the crowd, leading her to feel she messed up and run off in tears. When Papple attacks with another Oshimaida, Hana finds herself unable to transform, forcing Saaya and Homare to fight without her. Just as things look desperate, Hug-tan uses her own asu power to protect Hana and defeat the Oshimaida, falling into a deep sleep as a result of exhausting herself.

With Hug-tan ending up with a fever as a result of exhausting her asu power, Hana blames herself, feeling she doesn't deserve to be a Precure as she doesn't have anything special she can do. After Sumire gives her some comfort, Hana is approached by Saaya and Homare, who assure Hana that it is her special qualities that helped them. Following a hint from the Mirai Pad to go to the Nobinobi Tower, Hana has Hug-tan hear her heartbeat, allowing her to recover. Just as Hana runs into the man from before, the tower is attacked by Charalit, who has been transformed into an Oshimaida himself. Once again able to transform into a Precure, Hana gains her second Mirai Crystal which transforms into a magical sword. However, Hana chooses not to attack, sensing that the real Charalit is still inside the Oshimaida, becoming consumed by his insecurities. Sympathising with Charalit's pain, Hana transforms the sword into the Melody Swords, allowing the Cures to purify Charalit, after which Hug-tan calls Hana "Mama".

The girls hold a pajama party at Harry's store, during which they discover Hug-tan has grown some teeth. After the girls watch some scary movies, Harry explains that he and Hug-tan both came from the future. Just then, Papple summons a Vending Machine Oshimaida, but the Cures use their Melody Swords to defeat it. Afterwards, the girls spend the remainder of their pajama party chatting all night. The next day, Ruru alters Sumire's memories in order to infiltrate Hana's home as a family friend from abroad.

To aid in her mission of observing Hana, Ruru transfers into her class under the name Ruru Amour, excelling in both studies and sports. Hana's family tries to hold Ruru a surprise welcoming party, but she seems disinterested, claiming there is no logical merit to it. Later, Hana goes searching for Ruru amidst an Oshimaida attack, unaware that she is the one who summoned it. When Ruru questions Hana over why she feels the need to look for her, she is taken aback when she tells her she wants to be her family.

Ruru joins the others as they spend the day looking after babies at a daycare. As Ruru quickly scans a textbook to learn how to look after the babies, Saaya starts becoming competitive with her over their affections. Later, Ruru summons an Oshimaida in order to split the Cures' attention between fighting it and protecting the frightened children. However, Ruru then has a change of heart, stepping in to protect the children while the Cures defeat the Oshimaida.

Sent on an errand to buy some eggs for the Nono family, Ruru comes across Emiru, who has made her own PreCure persona to try and help others. Taking a liking to Ruru, Emiru invites her to her house to play her guitar for her. When Emiru's brother Masato claims that the guitar isn't fitting for a girl, Ruru gets upset and stands up for Emiru. As Papple sends in another Oshimaida to attack, Emiru rushes in to save a child from danger, earning praise from the real Cures.

Homare's classmate Aki asks her to teach her how to skate, much to the ire of her friend Junna. As Homare remains conflicted over what to do, Ruru steals her PreHeart under orders from Papple, who targets Aki and Junna to summon an Oshimaida. As Hana and Saaya struggle to fight the Oshimaida on her own, Ruru makes the decision to return Homare's PreHeart so she can aid them. Noticing Homare's efforts to save them, Aki and Junna make up with each other, weakening the Oshimaida and allowing the Cures to defeat it. As punishment for her actions, Ruru is hit by a beam that shuts her down and is taken away by Papple.

In addition to deleting the memories that Ruru had made with everyone, Criasu member Listle reprograms her with a battle protocol. Meanwhile, Harry explains that Ruru is an android sent to spy on them, but the girls remain determined to save her. Following her reprogramming, Ruru equips a battle suit and confronts the Cures, using their battle data to predict their moves. As Ruru tries to obtain more data from the Cures, she starts to regain the memories that she herself prevented from being deleted. With help from Hana, Ruru gains a human heart and turns against the Criasu Corporation. As Ruru finally rejoins the others, Emiru discovers the Cures' secret identity.

Ruru undoes the memory manipulation on Hana's family, but finds she is accepted all the same. The next day, Emiru confronts the girls about their secret identities, asking to observe their daily lives to see what makes them so special. As Ruru starts to worry that she lacks a heart like others, she experiences a sudden system error, leading the others to tell Emiru that she is an android. As Emiru worries about how to help Ruru, Papple attacks with a Oshimaida with the ability to change forms. As Emiru helps Ruru stand up to Papple, the Cures manage to defeat the Oshimaida, after which Emiru and Ruru bond over music.

Having observed how well Ruru and Emiru match each other, Henri invites them to take part in a hero-themed fashion show with him. As the girls help designer Rita Yoshimi prepare for the festival, Masato tries to force Emiru to come home, claiming only boys can be heroes, but Henri stands against him while wearing a dress, revealing that he wears what he wants to wear. As new Criasu employee Gelos targets Masato to summon another Oshimaida, Henri notices Masato's frustration and encourages him to love himself, allowing the Cures to defeat the Oshimaida. With the fashion show a great success, both Ruru and Emiru aspire to become PreCures, only to discover there is only one PreHeart available.

With only one PreHeart left, Ruru and Emiru are left conflicted over the fact only one of them may get to become a PreCure. As Hana gets a cold trying to wish for a miracle, Homare and Saaya tell Emiru and Ruru about the miracles they've experienced, while Masato decides to give Emiru his support in becoming a musician by giving them concert tickets. As Emiru and Ruru attend the concert together, Papple attacks with an Oshimaida. As Emiru and Ruru both receive Mirai Crystals, their desire to both become PreCures together transforms the remaining PreHeart into two, allowing them to both transform into Cure Macherie and Cure Amour respectively and defeat the Oshimaida.

While excited about being a PreCure, Emiru feels downhearted over not a failed attempt at patrolling the town while Ruru becomes worried about her after Emiru lashes out at each other. After some encouragement from Homare and Harry, Emiru comes to understand the happiness that came from becoming a PreCure alongside Ruru and sorts things out with her. After Emiru's guitar gets destroyed during a battle with an Oshimaida, Hugtan, hearing her plea for an item akin to the Melody Sword, opens a portal that summons two PreCures from another world: Cure Black and Cure White.

Cure Black and Cure White, whose real names are Nagisa Misumi and Honoka Yukishiro respectively, assure Emiru and Ruru that it's okay to butt heads with each other sometimes. Letting out their true feelings and making up with each other, Ruru makes new guitars for her and Emiru while she makes matching bracelets. Meanwhile, Papple, feeling despair over seeing Gelos with her boyfriend, transforms herself into an Oshimaida. As Nagisa and Honoka assist the other Cures in fighting Papple, Ruru and Emiru venture inside the Oshimaida to remind Papple that she still has love. Gaining a new power, the Twin Love Guitars, the two Cures manage to purify her Oshimaida, after which Hugtan sends Nagisa and Honoka back to their world.

As Hana tries to figure out her own goal, she once again comes across the mysterious man, who explains his desire for an ideal world. Just then, Criasu employee Daigan attacks with an Oshimaida, only for another employee, Dr. Traum, to show up and eliminate him, transforming the Oshimaida into a more powerful Mou-Oshimaida. It is then revealed that the man Hana met is CriasuCorp's president, George Cry, who steals all of the Mirai Crystals and uses them to stop time. As Cry attempts to kidnap Hugtan as well, Hana manages to break free and save her, restoring time and allowing everyone to defeat the Mou-Oshimaida. As the Criasu team add another evil employee named Bishin to their forces, Harry keeps a secret from everyone that he is in possession of a white Mirai Crystal.

Shocked to find the town's local night pool event is lacking sense compared to what she pictured, Hana and the others help out to make the pool more stylish by the time it opens. As the girls enjoy the event, Hana tries to hide from everyone how shaken she is over her encounter with Cry.
