安場 琥珀

Raito's elder cousin. They currently share an apartment.
Kohaku considers Raito her younger brother since they grew up as siblings. She believes her feeling for him is "family love."

An honor student, Kohaku leads the school's theater club and is ambitious, yet she is sloppy at home and has trouble getting up in the morning. Raito typically cleans her room and helps her wake up.

Likes: Raito's cooking, the sun
Dislikes: Waking up in the morning, clock alarm
