Mayu is a teenager with dull green eyes. Her brown hair is styled into a small ponytail at the top right side of her head, held by a hair tie with two pink spheres. Her bangs are kept back with two orange barrettes.
Mayu is an extremely kind and sweet girl, who cares deeply for her friends. She has a crush on Morishige, but often pushes it aside. She's all too willing to risk her life for her friends and family. Oddly enough, she has a dark side. This side is manipulative and ruthless.
Mayu, despite being deceased, is still the same girl she was in life. However, she ceaselessly searches for her "Shige-Nii", and is almost never NOT searching for him. She retained her "dark side" in death.
- She's extremely talented at acting, and as a result of this, can lie easily.
- She understands Zalgo language, but despises it.
- Whenever someone insults Morishige, Mayu will lose her temper, and attack whoever insulted him. This goes for all of her friends.
- She gets scared easily, and will often flee from terrifying situations. This is what led to her demise.
