Mario Gender: Male Birthday: February 29th Favorite Food: Chocolate Appearance: Shaggy black hair, tanned skin, and dark circles under his eyes. A first-year student at Paparajuku Bachiriko Academy High School, in the class next to Amari Katasumi. He has a very, very severe case of chuunibyou and often uses the phrase "Whatever, it doesn't matter." He is incredibly talented at singing and is also skilled at playing the electric guitar. He loves rock music and is the guitarist for the band club, but he's a problem child who rarely listens to others. He gets along with Amari like they're siblings. He gets annoyed if people try to ship him with Amari; they are strictly friends and nothing more. He wears strawberry-print underwear, a fact only Amari knows (and she teases him about it constantly).

A first-year student at Paparajuku Bachiriko Academy High School, in the same grade as Mario. Outside of PriPara, she is clumsy at grooming herself and has messy, grass-like green hair. Inside PriPara, while her bangs and side-locks remain the same, her hair grows long and transforms into curly twin-drills, changing color to a sky blue close to mint. Her default outfit outside PriPara is her school uniform; inside, she wears a hoodie with rabbit decorations and a short skirt. She is an extreme introvert (MBTI: I) whose only friend is Mario, and she finds it difficult to talk to people. Her favorite food is wasabi mayonnaise. She bickers with Mario frequently and they act like siblings (though they are not related). She isn't shy at all when dealing with Mario.
