Onipan!

In a world where humans and demons coexist, three plucky oni kids are on a mission to improve their image. Armed with magical underpants, they transform into humans and enroll in a Tokyo high school to learn about love, friendship, and superpowers. Join Tsutsuji, Himawari, and Tsuyukusa as they take on projects to beautify their city, help with school festivals, and even become idols! With their newfound popularity, they'll show the world that onis can be more than just scary demons.
