Sayo AISAKA

Aisaka Sayo occupies seat number 1 of Class 3-A. She is the ghost of a student who died 40 years ago of unknown causes - even Sayo herself cannot remember the circumstances surrounding her own death. Despite being a ghost, she is afraid of scary things. Most other students cant see her, and when they do they perceive her as some sort of evil spirit, when all she wants to do is make friends. However, she becomes close friends with Kazumi and follows her wherever possible.
