Plot
Continuing off from the last episode, Emiru introduced the Precure to Hana, who had come to visit her fellow Cure after she and her brother Masato moved to Yokohama as a means of living on their own for a change. Aya is excited as she gains the former Cure Yell's signature, despite already getting a signature from one of the HUGtto Pretty Cure, much to Emiru's amusement.

Meanwhile, Mio was fixing up an abandoned apartment as her temporary home after she was kicked out from her own home. As she finished re-furbishing her room, a mysterious crow began to watch the girl as she went out to pick up some food.

Back with the Precure, Emiru had invited Hana and the Precure over to her house and was showing her friend the sights when the former Cure Yell noticed a familiar boy wandering the streets. Confused by this, Hana begins to walk upto the boy but he immediately vanished. When the Precure asked her what was wrong, the former Cure Yell said that she saw Clover once again.

Seeing the confused looks on their faces, Cure Yell quickly explained the story of how she, Saaya, and Homare encountered Clover along with the Kira Kira Pretty Cure A La Mode, and the Mahou Tsukai Pretty Cure. This shocked Saya as she did not know about this adventure from Riko, but soon a voice stated that it was true.

When the group turned to find out where this voice came from, they were met by Asahina Mirai, the former Cure Miracle, and her teddy bear Moforun. This caused both Saya and Aya to squeal with glee as both fangirled about seeing both Hana and Mirai on the same day. Meanwhile, Moforun said hello to the team of partner fairies as they exchanged pleasantries.

Back with Mio, she left a convenience store with some food for herself when she noticed the crow from before just staring at her. This confused her at first, but she shrugged it off as she continued on like it was normal.

As the Precure had invited Mirai and Moforun along, they soon ran into the young boy once again as he crashed into Maya. Flustered, both the boy and the young Precure quickly apologized to one another as they got back up. The boy admitted that he wasn't used to the bustling streets before but he soon made a run for it. However before he could, he immediately recognized Hana and Mirai as they did the same.

However before the Prism Hearts Cures could figure out how this boy knew their names, Dark Onibi and Bottom had arrived. When the Precure wanted to know what they were doing here, Dark Onibi revealed that he wanted to study Clover, the boy, after he had somehow found a way to live after he left his world.

Not wanting him to get his hands on the boy, the Precure transform and battle against Dark Onibi's squadron, performing an all-pink, all-blue, and all-yellow Prism Change during the battle. Annoyed by seeing this, Bottom decided to try and go for the young boy, but the three veteren Cures were not having that as they fought off the general unmorphed.

During the chaos, Clover quickly makes a run for it while Dark Onibi gave chase. Not wanting the scientist to get his hands on the boy, Cure Papillon broke off from the team to try and prevent the general from kidnapping Clover alongside Hana.

During this chase, Cure Papillon finds a Cure Whip Prism Card, which she instantly performs a Prism Change with in order to use the Kirakiraru to create a barrier between Dark Onibi and Clover. With her help, the three were able to escape from the former director and find themselves alone in a park.

When Maya asked the boy how he had gotten here, Clover explained that one day, Dark Onibi had mysterious vanished from his world after he left to get some firewood. When he tried to find him, he ended up stumbling across the Great Heart Tree, which seemed to give him temporary immunity while travelling between worlds. It was there that he had arrived in Yokohama and learned of Darkest Day, which saddened the boy..

After Clover had finished his story, Hana saw that the mere mention of Darkest Day brought sadness to the young girl. Maya then told her predecessor that during that day, Maya almost died after she had gotten stuck in a collapsing building. At first, she was terrified and was pleading for someone to save her and, even after the Precure had done so, the memories of that day had never left her.

Hana soon realized that Maya was the very same girl she had saved that day alongside Nozomi, which surprised the two as Hana gave her story and stated that she and Nozomi were fighting side-by-side when she noticed Bottom try and collapse a building onto the two Cures. They were able to dodge the attack, but soon realized that there were civilains within that building and so, the two rushed

The two soon hugged before quickly pulling back in embarrassment after Hana teased the duo. It was then that Dark Onibi had grabbed Clover while the two were distracted. However before he could run off with the boy, Maya transformed into Cure Papillon once more and used the Flutter Dream to bind the general and save Clover. She then performed a rapid-fire Prism Change into Cure Rosette, Cure Pine, and Cure Lemonade before sending the general flying with the Butterfly Spike.

Back with the Precure, they had just used the Blooming Fortissimo and the Marble Screw to send Bottom packing when they noticed that Cure Papillon and Clover was missing. Before they could try to set out to find them, Maya and Clover were able to get back to the group. Afterwards, Clover decided that he had spent enough time in the human world and went back to his world, but not before telling Maya thank you for what she had done.

Afterwards, the group had arrived at Emiru's house and decided to simply hang out for the rest of the day. Meanwhile, Dark Onibi and Bottom were growling that they had suffered yet another defeat. Fusion, not wanting his fellow generals to suffer Black Hole's punishment, suggested that they find a way to de-power the Precure somehow.
