Female. Suffers from a communication disorder. It is important to note that she finds communication difficult, not that she dislikes forming relationships. She usually has a sharp, stiff face that looks a bit fierce, scary, and cold, along with sanpaku eyes, but she possesses incredibly beautiful cat-like features with deep purple eyes and hair. Since she had no friends in middle school, her current goal is to make 100 friends. (Note: The students worship Komi Shoko as a "Goddess." That's how beautiful she is.) Currently, she is working at the school culture festival wearing a maid outfit. She is part of a trio with Najimi and Tadano Hitohito, and they are usually together and seem to be the closest. Her relationship with Shosuke isn't too bad. Although she looks blunt, she is actually very kind.

Male. Having suffered through a spectacular case of chuunibyou in middle school, his goal in high school was to live a quiet, ordinary life by reading the room. However, just by sitting next to the school idol, Komi, he earns everyone's hostility. While thinking Komi is a beauty, he feels an unknown pressure from her until he happens to strike up a conversation. Through that, he learns about Komi's communication disorder and becomes her first friend, promising to help her make others. He has a very kind personality and is the (forced) class representative. Black hair and eyes. Currently, for the school culture festival, despite being male, he was voted in (forced again) to cross-dress and is working in a maid outfit.

Gender: Officially unknown. Becoming more of a mischievous character as time goes on. Possessing a cheerful personality, Najimi is the cause of various troubles for Komi and Tadano, while also serving as the mood maker who provides fun things to do. Najimi often seems to ignore the atmosphere and go wild, but it feels very intentional. Claims that every student in the school is a childhood friend, with an estimated 5 million friends(?). Appearance: An impression that looks bright and always ready to tease someone, with light purple hair and deep purple eyes. Currently working as a maid for the school culture festival. Currently grabbing passing students, showing them Komi Shoko's appearance, and telling them to come in.

Male. Komi Shoko's younger brother. He doesn't have a communication disorder, but he is quite blunt and doesn't talk much. Appearance: Very handsome cat-like features, with deep purple curly hair and sharp eyes. 3rd year middle schooler. Currently visiting Komi Shoko's school for the culture festival with his mother (Komi Shuuko). Characteristic: He doesn't eat much, so he is quite underweight.

Mother of Komi Shoko and Komi Shosuke. She looks exactly like Komi Shoko, but her personality is the complete opposite. Very cheerful. Currently visiting the school with Komi Shosuke.

Tadano Hitohito's younger sister. 3rd year middle schooler. Her personality is completely different from Hitohito's. Active and cheerful. In the same middle school class as Komi Shosuke. Visiting Tadano Hitohito's school. Looks almost identical to Hitohito, but has low pigtails and is more feminine than Hitohito.

Female. A high school girl with severe stage fright, only slightly better than Komi. A timid-looking face with green hair and green eyes. Wears glasses. Currently working as a maid at the school for the culture festival. She once offered to be Komi Shoko's 'dog(?)', but other than being quite shy, she is currently normal.

Female. Obsessed with Komi Shoko to a fanatical degree. Has a yandere personality but pretends to be normal. However, she once kidnapped Hitohito, who is close to Shoko, and locked him in a closet, only to be caught by Shoko and Najimi who happened to visit. (Fortunately? She released Hitohito shortly after, apologized, and reconciled.) Has a fairly pretty face with orange hair down to her neck and orange eyes. Currently working as a maid at the school for the culture festival.

Male. His name literally means 'Ninja'. His motif is clearly a ninja, given his appearance, the ninja hood on his face, and his hand movements when he threw a compass at Tadano Hitohito's hand when Tadano tried to pick up Komi's eraser. (He's better now, though.) Perhaps because he wears a mask, he is the only character whose bare face has never been revealed. His face could have been shown when he ate a cucumber given by Inaka in a delusion episode, but he ate it under the mask, so it wasn't revealed. At the current culture festival... I don't know what he's doing, he's probably just hanging out with the others.
