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 a bit cold and intimidating, she has many expressions and is quite cute on the inside. A classic gap-moe character. Straight purple-black hair, black eyes. Possesses doll-like beauty; her sanpaku 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 normal high school girl. Uses polite speech. Her goal is to make 100 friends; Tadano was her first friend and promised to help her. She currently has a crush on 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. Actually, 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. Tadano's best friend who knows all about his 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 dislikes conversation and has voluntarily established a stoic persona. Judging by how he acted when Shoko dragged him out to buy Christmas presents, he seems generally blunt and finds everything bothersome. He doesn't have a communication disorder; he just finds it tedious, so he speaks properly when the situation absolutely requires it. If Shoko takes after their father's personality, Shosuke is a mix of the father's silence and the mother's 'my pace' attitude. True to the Komi family's superior genes, he is a beautiful boy who is omnicompetent in everything except social interaction. Purple-black eyes and black hair. Like his 'cool beauty' sister, he is worshipped by the girls at school as a god and a 'cool city guy'. He is treated like a top-tier idol. However, since he avoids communication by choice and could be popular if he wanted to, he is the actual realization of the persona people mistakenly project onto 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. His room is equipped with various exercise equipment, suggesting he works out regularly. Like his sister who enjoys reading manga, subscribing to magazines, listening to music, and watching dramas, his hobbies are all home-oriented. He is even more of a homebody than Shoko; while Shoko makes a big resolution like 'I can do this' before going out for errands, he rarely leaves, and if he does, he finishes the 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 sanpaku 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 stoic. 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's height comes from his genes.
