Shirogane Tsumugi

Tsumugi is a tall young woman with incredibly long, wavy teal hair that reaches her knees and soft blue eyes behind round-framed glasses. She typically wears a dark blue school blazer with an orange ribbon tie and a pleated grey skirt. Her design is intentionally modest and unassuming, reflecting her self-proclaimed 'plain' nature.

Plain, polite, obsessive, deceptive, fanatical, observant, and cold-hearted.
