宮城野 紗由

A first-year student at Kotogaoka Academy, she is a girl who always carries a doll with her.

She is an extremely fancy girl, always carrying a doll named Sayurin that resembles her, and wearing a headband with unmistakable cat ears.

With a cheerful and innocent personality, she appears younger than her actual age, both mentally and physically.

Rumors say that Sayurin can actually speak, though the truth remains unclear. According to the girl herself, it’s something like ventriloquism, yet not quite…

Witness accounts suggest that Sayurin, in contrast to Sayu, makes very cold and cynical remarks.
