Mai's older sister. Graceful as ever and popular with the boys, in reality, however, she's lazy and sees the world around her as bothersome. Her adoration from other girls has gone up of late, but she has no eyes for anyone else except for Mai.

After knowing that her sister will support her whatever the circumstances may be, Mayu has gotten more confident about being her true self. Despite trying to thank Mai for that, she still can't be honest with herself yet…

Since she pushes her tedious, everyday necessities on Mai (doesn't mind it at all), Mayu is pretty bad at the basics of domestic chores but has been helping Mai out lately and has even reached a point where she can cook on her own, though her room is a mess. Mayu is also currently a member of the art club.
