The Class Rep for Class 2-A. She is in the same class as Junichi, Kaoru and Masayoshi. She is very hardworking and a model student.
Ayatsuji-san is everyone's idea of a model student. She is the class rep, is heavily involved in student council and heads the executive team for the Founder's Festival each year at the school. However, as Junichi gets closer to Ayatsuji in her arc, it turns out this image of a perfect student might be somewhat fake. Ayatsuji has a complicated but interesting personality. She seems to have her whole future planned out ahead of her. One thing she isn't so prepared for is love.
