Hiwa Natsunagi is a high school student living in Iwaki City, Fukushima Prefecture. Worried about what to do with her life after graduation, she spots a poster for Spa Resort Hawaiians the “Hawaii of Tohoku” the place where her sister Mari used to work and applies to their new dancer (hula girl) campaign on a whim. Despite her lack of experience, Hiwa is accepted for the job, and starts on the path towards becoming a Hula Girl with her classmates, Kanna, Ranko, 'ohana and Shion. However, unable to keep in step with one another due to their differing personalities, their first stage ends in disaster. Called the “most pitiful rookies ever” the girls are disheartened, but they learn to share the good and bad...and strengthen their bond despite the occasional fumble. With their hearts and minds firmly set, the girls grace the stage once more.

Class 1-A visits Nabu Island where they finally get to do some real hero work. The place is so peaceful that it's more like a vacation... until they're attacked by a villain with an unfathomable Quirk! His power is eerily familiar, and it looks like Shigaraki had a hand in the plan. But with All Might retired and citizens' lives on the line, there's no time for questions. Deku and his friends are the next generation of heroes, and they're the island's only hope.
