Himiko Agari is the glasses girl who has been a member of Library Committee for a year. She finds solace in toilet stalls as she's weak against peer pressure, having no confidence in herself. Himiko has green hair which she ties up, green eyes and a pair of glasses. 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. She secretly adores Komi Shouko and initially refuses her friendship at Tadano Hitohito's suggestion as she thinks she only fits being Shouko's dog.
