A perverse individual who adores anyone and anything that's fragile and child-like. He sometimes blurts out his true thoughts without thinking. Though he has a cowardly and servile personality, he can't ignore a person in need. He seems to struggle with going out in public. With a voice that wavers deeply as he sings, his performances are soft and lingering.

Mayoi is a member of Starmaker Production's ALKALOID.
