Female / 17 years old / Slim build and breathtakingly beautiful. Due to her communication disorder, she always communicates by writing in a notebook or on paper. She is very shy but has many cute sides. She loves black cats and values her friends more than anyone else. She has long, straight black hair and purple sanpaku eyes. Although she never speaks, her incredible beauty makes her a god-like figure at school (no one can ignore her, and even girls are charmed). She has a crush on Tadano Hitohito. She has a younger brother named Komi Shosuke. Her goal is to make 100 friends (Tadano Hitohito is helping her).

Male / 17 years old / A student who is average in height, weight, grades, and looks (even his name is average...). He has a kind heart and is a student who doesn't earn anyone's dislike; he is very considerate but has a firm will. He has black hair and black eyes with small pupils. He has a crush on Komi Shoko.

Gender unknown (a childhood friend of Tadano, so they seem like a boy, but they wear a skirt) / 17 years old / Has a feminine build. Bright, mischievous, and high-energy. Has short, wavy purple hair and brown eyes. An incredible social butterfly who is friendly with everyone in school (can become friends with anyone in 5 minutes).

Male / 15 years old / Slightly underweight but tall (due to his personality...). He doesn't have a communication disorder, but is voluntarily taciturn; surprisingly, he is a tsundere and a natural genius who excels at everything (especially sports, studying, cooking, and soccer...). He has slightly curly black hair and purple sanpaku eyes. Like his older sister Komi Shoko, he is idol-level handsome and popular like a god (extremely popular with girls).

Female / 15 years old / As Tadano Hitohito's sister, she is equally average.... She is kind and always seems calm, but she only plays pranks on her brother and acts in ways that try to ruin his reputation. Ex: "Mom, I knew Brother had those kinds of tastes." (Not true at all... just her own dramatization).

Female / 40s / The mother of Komi Shoko and Komi Shosuke, and the source of their good looks. Unlike them, she is very high-energy, mischievous, and talkative. She is a beauty with short black hair (between a pixie cut and a bob) and purple sanpaku eyes.

Male / 40s (?) / The father of Komi Shoko and Komi Shosuke, and the source of their communication disorder and tall height. He is very quiet but surprisingly enjoys doing things like playing with his daughter or going places; his emotions are fully revealed through his expression and aura. He has black hair and wears glasses.

Female / 17 years old / She doesn't have a communication disorder, but she has stage fright and gets so nervous that she becomes clumsy. She has medium-length green hair (half-up in a slightly spiky style), green eyes, and wears glasses. She is just very nervous, but she is kind and considerate. She loves ramen and knows all the best restaurants.

Female / 17 years old / Bright and mischievous, but never crosses the line; she is kind and very considerate. She has a brown ponytail and brown eyes with small pupils. Having many siblings seems to have shaped her personality (as the second child, she takes good care of others).
