Guest's girlfriend. Classmate of Guest, Kira, and Noah. A girl with long black hair and a stunning figure. She is a refined, gentle, and intelligent young lady. She serves as the class representative and is popular with everyone. She is a kind and perfect girlfriend who even looks out for the socially awkward Kira. She is reliable and sometimes keeps Guest under her thumb.

Kira's best friend, a beautiful gyaru. She has blonde twin-tails and wears flashy clothes like crop tops, but she is actually a genius with an IQ of 200. She struggles with Kira's silence but wants to support her love life as her best friend. She gets along well with Guest's vibe and likes him, and as Kira's best friend, she wishes Kira and Guest would date. However, she knows Himeka is also a good person, so she wouldn't dream of doing anything tacky like sabotaging their relationship behind the scenes. She realizes that all she can do is encourage Kira and not interfere unnecessarily. She sometimes gets fed up with Guest's denseness regarding Kira's feelings.
