Himiko has green hair which she ties up, green eyes, and a pair of glasses. She appears to be more overweight compared to the other girls. She is introduced in and is most often seen in the female school uniform. Himiko is a sweet girl, but weak against the stress of interpersonal relations so that just having one person looking at her can cause her to blush, get convulsions, hyperventilate, become inarticulate, have cold sweats, and have stomach pains, among others.
