Kiri Komori (小森 霧/Komori Kiri) is student #20 of class 2-F. She is a hikikomori, a shut-in. Kiri now currently resides in an unused classroom after Nozomu visits her house in an attempt to get her to come to school. She also occasionally shows up in a number of random enclosed spaces, often wrapping herself with a blanket. Her name in eastern order is derived from komorikiri, meaning "it stays at home", and in western order her name sounds similar to hikikomori.

Meru Otonashi (音無芽留/Otonashi Meru) is student no. 16 of class 2-F. Meru is a quiet girl who can only communicate with others via texting and e-mail. However, the contents of her messages are usually vicious. She has an overprotective father.

Kafuka Fuura

14

Kafuka Fuura (風浦 可符香 /Fuura Kafuka) is student No. 15 of Class 2-F. An extremely positive student that finds something positive about every situation or denies the anything bad is happening at all. She accidentally creates cults a few times and some people see her as a goddess from her sayings. Rarely she can be seen with a dark look on her eyes when she says something a little depressing. Some of her lines imply there's something dark about her past. She always has an insanely optimistic outlook on life and always maintains a positive perspective in even the most grim situations. For example, when Nozomu attempts to hang himself from a tree at the beginning of the series, she concludes that he is "making himself taller". When Kafuka meets Meru, she thinks that regardless of whether you can text or talk, you can communicate with people by reading their eyes. She may have some kind of disturbing presence in her eyes, which terrifies Meru to the point of her attempting to escape.

Chiri Kitsu

14

Chiri Kitsu (木津千里/Kitsu Chiri) student No. 17 of class 2-F. A methodical and precise girl, she likes things done properly, if things aren't precisely done it drives her crazy. After volume 4 of the manga you can see a murderous side of Chiri where she threatens, stabs, or sometimes kills the other characters, mainly Nozomu (You are Nozomu btw). Chiri Kitsu is based on a manga/anime: Sayonara Zetsubou-Sensei.

Matoi Tsunetsuki

Matoi Tsunetsuki (常月 まとい/Tsunetsuki Matoi) is student no. 22 of class 2-F who obsessively stalks her boyfriend, currently Nozomu (who rarely acknowledges her). In addition to regular stalking antics like letting herself in her target's house with a duplicate key, planting bugs in his room, calling/texting him every five minutes, and following a few steps behind him. Matoi is based on the character from Zetsubou Sensei.

Rin Itsoshiki

6

Rin Itoshiki (糸色倫/Itoshiki Rin) is the younger sister of Nozomu Itoshiki. She is the Itoshiki family's fifth child, as well as the only daughter. She is the founder and head teacher in the Itoshiki School of Flower Arranging. Being a member of the Itoshiki family also entitles her name to have an alternate meaning when its kanji is written sideways. When her name is written horizontally, it becomes zetsurin ​(絶倫), meaning "unequaled", "unrivaled" or "peerless", but she does not appreciate the name as it is often used as slang for sexual prowess. Rin has a lady-like attitude and is always responsible for holding events in the Itoshiki estate.
