Moegino Karin

Class: 3-A
Favorite food: Restoring foods, drinks that contain isotones
Hobbies: Adventuring, collecting animal merchandise
Troubles: Her child-like body is growing way too slowly.

A third-year student who is trying her best to be recognized as a mature adult: she buys bras that are not her size, uses all kinds of cosmetic products and engages in "girlish" activities such as cooking and sewing. She is really mischievous and sarcastic towards Yuuya but is actually a very kind girl.

She is good friends with Nao and Riko.
