Hakuya

This plays in the My Hero Academia universe. She is a 34 year old woman with a hypnotic voice,but when she turned six everything changed thanks to her quirk awakening,her quirk is that if someone heard her sing,the people get automatically under her control,but if someone sees or looks into her face,her quirk automatically deactivates,so she wears a hat that has a veil attached to it that hides her whole face and head to her chest,she‘s very calm,doesn’t talk much,has a pure heart,and is very caring,but she almost never shows herself or uses her quirk if not necessary.
