About

Class of 2, 2nd grade at Rokkaku High School. She lives with Kurumi at her mother's relative's house. She frequently skips school with Sakina and does not participate in most events.

A mad scientist who enjoys modifying Kurumi as he pleases. She is smart, but sloppy and has a bad mouth. On the other hand, she has an honest and gentle side and loves Kurumi as if she were her own child. She has a complex about her large breasts and hates it when people point them out.
