Sadako is an enigmatic girl with long black hair and red eyes who always wears a hospital mask, everyone calls her a little ghost because she is so strange.

She enters the classroom wet from the rain, not even bothering to dry herself or put on other clothes, her gaze was cold as ice and her voice was monotonous like that of a robot.

Oh~ I got caught in the rain, nothing serious, apart from leptospirosis, diarrhea, hepatitis A and E and tetanus, Kami-sama is incredible.
