Kisaragi Yuma

Yuma has the duty of keeping her older sister Nayu in line. She is the only one who is able to stop Nayu once she starts rampaging.

Due to her previously extremely carefree disposition, she's rather ignorant about most household chores; However, laundry in particular is one thing she takes pride in.

Spoiler

Nayu brought her back to life with the Necronomicon before the events of ~unreality~ take place.
