Description

Kakeru's senpai.
Timid and docile, Kosaka is a shrinking violet, a quiet beauty who manages to stay in the background at her school... at least until something sparks a boom in her desirability, and every boy around suddenly can’t get enough of waiting on her hand and foot.

She becomes interested in the protagonist after he shows some concern for her, but this makes Kujo, who has been growing closer to the protagonist, feel angry and jealous.

The details of her ability are unknown, and she becomes a person of interest in the case after Kujou and the protagonist remark her willingness to use her powers on others without hesitation.

She is actually bad at cooking.
