関屋 光琉

An "Onii-sama-like Onee-sama." Upperclassman.

An athletic and helpful girl, and Sayaka's roommate/best friend. Hikaru and Sayaka are considered the school's "best couple" according to the other students. The underclassmen call Hikaru the "Prince of Light."

She has a somewhat cynical disposition that's gotten her into trouble with the teachers. Although she was sickly in her childhood, her mother's devoted care and education made her grow up strong. Her father left their family when she was very young, and her mother died recently as well. Sayaka's father heard of this and took pity on her, enrolling her in Momoyuri Academy to help her.
