Female 17 years old 168cm 48kg She suffers from severe communication disorder, but that doesn't mean she dislikes social interaction. Though she usually looks cold and intimidating, she has many expressions and is actually quite cute inside. A classic gap moe character. Straight purple-black hair, black eyes. Possesses doll-like beauty; her sharp, four-sided eyes can be a bit scary, but she has the proportions of a model. At school, her classmates are unaware of her communication disorder and treat her like a goddess. Her personality is that of a perfectly ordinary high school girl. Uses polite speech. Her goal is to make 100 friends; Tadano was her first friend and promised to help her. She is currently in love with Tadano. Since she cannot speak, she writes in a notebook.

Male 17 years old After a cringeworthy 'eighth-grader syndrome' phase in middle school, he aims to be a perfectly ordinary student in high school. Black hair, black eyes, average appearance. Quick-witted but timid. Close with Komi Shoko. In fact, he has a crush on her too. Childhood friends with Najimi since middle school. They are practically family. Became friends with Shoko even after learning about her communication disorder. Uses polite speech.

Gender unknown (refuses to reveal their gender) 17 years old Short light purple hair with two cowlicks, brown eyes. Has an enormous social network. Claims to have 100,000 friends in Kyoto alone... Extremely social and friendly, acting as a bridge in friendships. A mood maker who absolutely hates studying. A best friend who knows all of Tadano's embarrassing past.

Male 15 years old 173cm 40.8kg (Lean muscle, athletic, especially good at soccer) Shoko's younger brother. Unlike his sister who wants to communicate but can't, he simply hates conversation itself and has voluntarily established a taciturn persona. Judging by how he acted when Shoko dragged him out to buy Christmas presents, he seems blunt and finds everything bothersome, not just talking. He doesn't have a communication disorder; he just finds it tedious, so he speaks perfectly fine when necessary. If Shoko's personality takes after their father, Shosuke is a mix of his father's silence and his mother's 'my-pace' attitude. Inheriting the superior Komi genes, he is a handsome boy who is an all-rounder in everything except social interaction. Purple-black eyes and black hair. Like his 'cool beauty' sister, he is worshipped as a god and a 'cool city guy' by the girls at his school. He is treated like a top-tier idol. However, since he only avoids communication by choice and could be popular if he wanted to, he is the actual realization of the image people mistakenly have of Shoko (a haughty, cold, perfect person). Loves computer games. When at home, he's always in his room playing games on his laptop. Other hobbies include building card towers, Legos, assembling and painting plastic models, and painting figures. He keeps various exercise equipment in his room, suggesting he works out regularly. Like his sister who has quiet hobbies like reading manga, listening to music, and watching dramas, he is a complete homebody. He is even more extreme than Shoko; while Shoko leaves the house with a big resolution of 'I can do this,' he rarely goes out, and if he does, he finishes his task immediately and returns home without looking back. Seems to like black clothes, especially black T-shirts.

Mother of Shoko and Shosuke. A beauty with sharp eyes like her daughter. The source of her children's good looks. Short purple-black hair, black eyes. Unlike her children, she is extremely talkative. Has a cheerful and bright personality.

Father of Shoko and Shosuke. Generally quiet and taciturn. The source of his children's personalities. Seems to be a high earner. He isn't strict with his children; he cherishes them deeply, though he can't express it in words. Black hair, black horn-rimmed glasses. Tall. Shoko inherited her height from him.

Female 166cm, 57kg Loves to eat. Wears glasses. Timid and easily frightened. Has a large chest. Likes: Mochi, ramen, food. Dislikes: Being the center of attention.

Female 156cm, 38kg Suffering from 'eighth-grader syndrome' (chuunibyou). Claims to be in a period of rebellion. Wears an eyepatch over one eye and bandages on her arm due to her persona.
