Description
Sixteen-year-old Mayu Sakuma abandoned her modeling career immediately after meeting the Producer, choosing idol life solely to monopolize their attention. She cultivates a compassionate, friendly, and helpful image among fellow idols, appearing as a typical, determined teenager fascinated by romantic ideals such as the red string of fate. This persona shatters when the Producer is present, revealing an intensely obsessive and boundary-violating nature. She persistently stalks them, demonstrating notable stealth by breaking into their home, car, and restricted areas like hot springs to observe, appearing and disappearing at will.

Mayu exhibits low tolerance for lack of attention or interference with her time with the Producer, issuing passive-aggressive threats and demanding declarations of love. Rejection unsettles her, though she remains cooperative with idol duties when not fixated on the Producer. She typically refers to herself in the third person, shifting to first-person when her obsessive tendencies surface.

Her hobbies include knitting and cooking, activities sometimes implied to mask her stalking. She collects the Producer's personal items and shows no shame in exposing herself or making advances. An anime episode initially suggested romantic feelings for the Producer but revealed her fixation on a coworker instead.

Relationships with other idols vary: most find her cute yet eccentric, while perceptive idols recognize her potential danger and maintain distance. She belongs to the unit Masque:Rade with Karen Hojo, Miho Kohinata, Rina Tada, and Chieri Ogata. She shares duets like "Illusionista" with Sachiko Koshimizu and joint cards for "Gyutto Milky Way" and "Trust Me" with Hinako Kita. She also hides under the Producer's desk alongside Shōko Hoshi and Nono Morikubo, bonding over this shared spot.

Fandom speculation suggests her signature ribbons could function as weapons for strangulation or binding. Official media only implies violence during a Drama CD where she nearly resorted to murder before being calmed. Her quotes, like "This ribbon will always connect you and Mayu" and "Do you like me? Do you like me? Do you like me?" reflect her fixation on eternal connection and validation.

Physically, she possesses a petite, curvy frame, drooping dark teal eyes, and medium-length pale brown hair with straight bangs, often adorned with ribbons or vivid pink heart-shaped motifs. Her official measurements are 78-54-80, though comedic material shows her altering these through concentration.
