安場 琥珀

Kohaku is a Raito's cousin who is a year older. They currently live together in an apartment.
Since they grew up together as brother and sister, she considers Raito to be her younger brother. She believes that her love for him is "family love."

At school, she is the director of the drama club, and she is considered an honor student; she has good grades, is good at sports, and ambitious - but she is sloppy at home and extremely bad at waking up in the morning. Raito usually cleans her room and helps her waking up.

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