Mutsumi

In the anime, Mutsumi is said to often skip classes due to sickness, disregards the proper uniform rule, and for some reason the teachers always forgive her. This causes her classmates to hate and bully her; saying that she is acting like she’s special when she's not, that she's annoying, and that she should just kill herself. In the manga, aside from the aforementioned personality she is also somehow childish, refers to herself as a third person, and doesn't get why people around her dislike her when she doesn't do anything to offend them. When Mutsumi complains about this to Yato, Yato points out that she is arrogant due to her attitudes and her way of thinking.

Mutsumi is a middle-school girl with long, brown hair tied in twin tails. Her eye color is green. She is seen wearing a grey sweater outside of her white shirt instead of a proper school uniform which is black and sits in the middle of her class.
