Fuyuko Mayuzumi

Fuyuko Mayuzumi (黛冬優子) is an idol from The Idolmaster: Shiny Colors and a member of the three-person unit Straylight alongside Asahi Serizawa and Mei Izumi. On stage she leans hard into a cute, sugary persona—cheery voice, flawless smiles, carefully chosen gestures—but it’s a deliberate mask she built after studying what gets fans’ attention. Offstage she’s sharp, pragmatic, and image-savvy, the kind of person who can read a room in a heartbeat and steer conversations to keep the spotlight where she wants it.

That duality is the core of her appeal. In Straylight’s edgy, dance-driven performances, Fuyuko’s precision and polish anchor Asahi’s wild instincts and Mei’s earnest power. Her stories revolve around ambition and insecurity: the fear of being “ordinary,” the pressure of maintaining a brand, and the slow, sometimes painful realization that trusting teammates doesn’t diminish her shine. Fashionable and meticulous, she treats every costume, line, and camera angle as strategy—yet beneath the calculations is a girl who genuinely loves the stage and wants to be adored for who she is, not just the character she plays.
