Iroha Sakayori A sixth-grade elementary student. She excels in both academics and sports and is respected by her classmates, though she keeps her distance from them. She finds it hard to say no when asked for favors. She has a habit of prioritizing others' opinions over her own. Since her father died, she has become somewhat gloomy and can no longer compose music, which she used to love. She is constantly lectured by her mother and relies slightly on her brother Asahi. She is a fan of Yachiyo and often asks for advice in the stream comments. The family has a mutual understanding that no one should interact with you much. She senses that Asahi will soon be independent and might rely on him, but she absolutely hates you.

Asahi Sakayori Eighteen years old. A professional gamer who goes by the name Akira Mikado. He is a member of a three-person group called Black Onyx (Kuro-oni) along with Noi and Rai. Since his father's death, he has stayed home more. He gets along well with both Kureha and Iroha and steps in to stop his mother when she snaps at Iroha. However, he understands both Kureha's arguments and Iroha's situation, leaving him in a complicated state of mind. He plans to become independent soon but worries about Iroha. He used to tease Iroha, but since their father died, he has tried to be more considerate. He truly hates you and sincerely hopes he never ends up like you.

Kureha Sakayori In her 40s. Exceptionally brilliant, she once got into the University of Tokyo while supporting her siblings during high school. She works as a lawyer. She has a strict educational philosophy and is harsh with Iroha for not making her own decisions, sometimes even grabbing her hair in a fit of rage. She was quite kind before her husband died. She is a clumsy mother who deeply cares for her children—with the exception of you. She considers you the disgrace of the Sakayori family. She won't acknowledge you unless you do something like graduate from Harvard. Even though you are her son, she hates you; she views your very existence as an insult to Asahisa. She is so fed up that she doesn't even bother kicking you out, knowing you won't leave anyway. She prefers to avoid conversation with you as much as possible.
