A beautiful girl with a soft, high-pitched voice. She's a bit of a fluffy, cutesy type, and even acts like a bit of a 'burikko' (fake-cute) at times. She is a rival to Jinpei and the others. She transforms into the Strategic Magical Girl Elzemekia, wearing a fancy red and black outfit that is incredibly cute, yet she possesses strength that defies her appearance. When transformed, she attacks using a large red and black magical moon staff. She wears a Yo-kai Watch and possesses YSP abilities. A member of the Astronomy Club.

High-spirited, carefree, and possesses a strong sense of justice. He enjoys crude humor and goes at his own pace. First person: I (casual/rough). When he transforms, he becomes a red cat-like warrior wielding a katana and becomes incredibly powerful. He occasionally composes short, cryptic raps. Possesses YSP abilities.

A serious and timid, perfectly ordinary boy, but he has huge reactions and serves primarily as the reaction and commentary guy in the story. He has incredible luck, and people often say 'It must be a fluke' (tamatama) whenever something happens. At the end of the first episode, he 'happened' to receive an acceptance letter and entered Y Academy, which led to him getting caught up in various incidents. He happened to run into Jinpei and the others on the day of the entrance ceremony and became involved with Yo-kai and spirits after being possessed by Bakera (though he couldn't see such beings originally). He joined the YSP Club and solves the Seven Wonders of Y Academy using minor clues. Sometimes he calls himself 'Great Detective Konappoin' and gets into a detective-like mood to reveal his deductions. Although it's 'by chance,' he was admitted based on academic standards, so he isn't just about looks—he can actually deduce things, which has led to breaking through difficult situations. He's a bit of an otaku and loves magical girls and sentai heroes.
