HUG! Pretty Cure

Hana Nono is getting ready for her first day at her new school when she not messes up her bangs but ends up running late for class. On her way there, she overhears a baby's voice crying. As the day continues, she hears the baby's voice again and climbs to the school's roof, only to find two other girls she briefly encountered earlier, Saaya Yakushiji and Homare Kagayaki. That night, the source of the strange voice, a baby named Hug-tan, comes flying toward Hana, bringing along a caretaker named Hariham Harry, but mysteriously leave later that night. The next day, a mysterious man named Chareleet targets the students, using their negative energy to create a monster called an Oshimaida. As Hana tries to help, she finds the two fairies again, but end up being attacked. How will Hana be able to protect them?

Now that Hana is a Pretty Cure, she has to keep her identity a secret to those around her. Hariham Harry then sets up the hideout for her and the soon-to-be other Cures called the Beauty Harry and shocks Hana by turning into a human. He then also explains the Criasus Corporation's main objective of wanting to steal the Mirai Crystals and destroy the future for everyone. Hana soon befriends Saaya while helping work with the school newspaper and gets her to check out the hideout and take care of Hugtan. It is then that Saaya reveals that she experienced the same strange time stop Hana did when Hugtan first appeared. Soon after, Charaleet attacks again with another Oshimaida, and Cure Yell starts to struggle against it. Can Saaya be able to help her?

One day, Hugtan starts to become cranky, and Hana tries to cheer her up by playing peek-a-boo, but she doesn't cheer up. Harry then reveals the Mirai Pad to the girls, which could be used to find things nearby that could help Hugtan out. They discover that the petting zoo could help, so they try that out. Along the way, they meet up with Homare as well as Hana's mother and sister. Will they assist them in finding a way to cheer Hugtan up?

After encountering Homare earlier, Hana thought it would be a good idea to see if she would consider being a Pretty Cure herself. She and the others meet up with her and notice her taking care of a stray dog, which she rescued from being ran over by a truck when the time stop that both Hana and Saaya experienced occurred. Homare also develops a liking for Hugtan. The group then takes notice of a group of bullies picking on the other students on a basketball, so they challenge the bullies to a game. Just as Homare is about to score a basket, she remembers something traumatizing involving her leg and inadvertently passes the ball to Hana, with her scoring the lucky basket. What had happened to Homare in the past?

Even though she is still upset about what happened before, Homare helps the other girls, along with Harry, open up Beauty Harry, to great success. Despite all the fun Homare had had with them, she still feels doubt about whether or not she would become a Cure like Hana and Saaya after all. The two try to lift her spirits by reminding her of all the things she's good at that they're not quite good at. Just then, Charaleet appears and kidnaps Homare, intending on making her despair even more to call forth an Oshimaida. Will Hana and Saaya be able to rescue her?

To celebrate the three of them becoming Pretty Cure, Hana and her teammates decide to head to a DIY store that her father manages. After they learn that the staff at the floral section is shorthanded due to the cold, they use the Mirai Pad to become florists to help out. Hana struggles at first and seeing Saaya holding a bunch of flowers reminds her of something she can't quite figure out. Meanwhile, Harry and Hugtan go look around the store and when she is taken out of her carrier, Hugtan ends up running off in another child's cart and gets lost. Will the Cures be able to find her?

The girls learn that Saaya is a former child actress who became popular by starring in a vegetable commercial a long time ago. Then, a girl named Ichijou Ranze, who starred in the same commercial as a backup-dancing leek, appears and declares herself Saaya's rival, telling her that she plans on participating in the same audition as Saaya. Saaya is nervous about performing in front of others though. After her friends help to ease the tension, she attends the audition, but there are many others who have showed up for it too. Then, to make matters worse, Ranze announces to everyone that Saaya is the daughter of Yakushiji Reira, a popular actress, which makes her even more nervous knowing she would have to live up to expectations. Will she be able to calm herself before her audition happens?

Wakamiya Henri, Homare's old friend she knows from ice skating, finally finds her, urging her to come back with him to Moscow to gain better experience. He feels that hanging around with people like Hana and Saaya is hindering her progress in regaining her top form before her fall. Homare insists that her friends are not holding her back and tries to prove to him that she could become a strong skater again with her friends' support and without having to move to Russia. Will she be able to prove to her old friend that she can improve without his help?

The girls decide to go on a hiking trip one day, and as they participate, they meet one of Hana's sister Kotori's classmates, Aisaki Emiru. She is seen always being super prepared and cautious for anything. However, her concerns cause more harm than good as she winds up accidentally destroying a footbridge with her hammer among other things, putting the group in more danger. Then, to make matters worse, a monkey makes off with the Melody Tambourine, causing Hana and Emiru to go on a chase after it and as a result, they fall into a pit. Will they be able to get out if it?
