Kukuri Tachibana  

, 橘菊理

A girl from school who resembles Kakeru's deceased sister is new at our school. She's one year older than Yuka and Kakeru, and she possesses the power to manifest her soul into an angel form called Abraxas. This angel appears chained and attacks with sharp blades sent out through chains. The girl is the adopted daughter of a renowned author in our area, having inherited their last name. She has no recollections prior to age 13 and seems to have lost her voice. To communicate, she uses a sketchbook.
