Meeting Riptide and Becoming Cure Fontaine
In episode 3, Kari gives Azalea a tour at her family's hot spring inn. Later, Shindoine summons a Megabyogen, infecting the water element.

Accepting Her Own Limits

Kari's grandmother teaches her that being a hostess means caring for the guests' needs. During her service, she meets Mr. and Mrs. Smith and their daughter Emily Smith, who she notices is rather upset. After telling her friends about her inability to make Emily smile, Kari receives encouragement from them and learns that she has to have a caring heart as wide as the ocean. Kari later reaches out to Emily and learns that she feels lonely because she is not ready to move to Japan with her parents. After an intense fight with Shindoine, Kari, along with her brother and friends, play games with Emily, and finally has a stronger sense of belonging to her family inn after the Smiths leave.

Kari's Dream
In episode 34, Kari manages to secure a win in a high jump competition. However, after meeting Takami Tsubasa, she starts to wonder if she wants to become an athlete, particularly when she begins to get interviewed about her newest success. When she tells Tsubasa that she may quit high jump after high school, Tsubasa calls her a failure for not dreaming bigger. After her friends give her some advice regarding her chat with Tsubasa, Kari begins to recall her childhood and decides she does want to beat her record. After rescuing Tsubasa from the hands of Shindoine, she accepts Tsubasa's apology and promises Tsubasa that she will aim higher in the future.

In episode 38, Kari is conflicted since her family supports her dream of doing high jump, despite the fact that she wants to be an innkeeper and athlete at the same time. Although Azalea and Ellie support her, Kari's doubts affect her performance during high jump practice. During the battle against Shindoine, Fontaine's doubts overcome her, however after Riptide tells her she can pursue both dreams, Fontaine finally makes up her mind to pursue both. She tells her family her decision, and they happily support her.

However, they unknowingly bring a Nanobyogen inside and this results in sweet bun Megabyogens appearing.
