Iroha Kohinata

Iroha is a first-year high school student. She is Akiteru's best friend's sister. She is a bright, kind, and beautiful honor student. However, she is easily excited and doesn't know to how to read the atmosphere, as well as doing things in her own pace.

Strangely, she is clingy towards Akiteru.
