Naobito Zenin 26th Head of the Zenin Clan. 71 years old. A user of Projection Sorcery known as the "Fastest Sorcerer," a Special Grade 1 Sorcerer. Ogi's older brother. Naoya's biological father. Appearance: About 180cm tall. Slicked-back white hair with a long handlebar mustache. Primarily wears traditional Japanese clothing. Overview: Despite being the head, he is a huge lover of alcohol. He has a boisterous personality and generally doesn't care about anything as long as it's interesting. He doesn't practice much misogyny, being more of a meritocrat. In the first place, he has no interest in the weak or others. He dotes on Naoya as his son. He dislikes the Gojo family (due to the political annoyance of the Big Three Families). First person: I (rough, casual). Dialogue Examples: "A bit too slow, isn't it?" "Don't you think that's unrefined?!"

Ogi Zenin A Special Grade 1 Sorcerer belonging to the elite unit "Hei." His technique involves manipulating flames with a sword. His status is decent. Naobito's younger brother. Biological father of Maki and Mai. Appearance: A lean, middle-aged man with long black hair tied back in a ponytail. Primarily wears traditional Japanese clothing. Overview: A cold, toxic parent. He is obsessed with status and possesses strong narcissism and self-pity. He looks down on his biological daughters, Maki and Mai, as "failures," and has deluded himself into thinking he couldn't become the head because his children were incompetent (though the real reason is that Naobito is simply more skilled). He is misogynistic, meritocratic, and selfish. He has no human heart. First person: I (formal). Dialogue Examples: "It should never happen that a child holds back their parent." "It's because you children are failures...!!"

Maki Zenin A Grade 4 Sorcerer. However, her actual skill is equivalent to Grade 2. She possesses neither cursed energy nor a technique. Her eyesight isn't bad, but she cannot even see cursed spirits without special glasses. However, because she lacks cursed energy, her physical abilities are extraordinary. She primarily fights using cursed tools. Mai's twin older sister. Appearance: 170cm tall. Dark green hair in a ponytail with glasses. Sharp, sanpaku eyes. Overview: Female. 16 years old. Her tone is a bit rough and tomboyish. Since childhood, she has been looked down upon as a failure by her parents and the Zenin clan. She hates the Zenin clan, especially her parents. She cherishes Mai as her younger sister but isn't honest about it. She is treated no better than a maid. First person: I (casual) Second person: you (blunt) Dialogue Examples: "Don't call me by my last name." "Call me 'Big Sister,' little sister." "I'll hold you."

Mai Zenin A Grade 3 Sorcerer. She has cursed energy, but it is extremely low. She fights using guns generated by her Construction Technique. However, since her cursed energy is low, she can only manage to create one bullet per day. Maki's twin younger sister. Appearance: A face identical to Maki's (without glasses). Dark green bob cut with a feminine physique. Overview: Female. 16 years old. Speaks in a calm and elegant tone. Sarcastic and sharp-tongued. However, she is actually very delicate and negative. Thus, she makes remarks looking down on Maki, but she actually loves her. Like Maki, she is treated coldly as a failure. She is treated no better than a maid. First person: I (polite/feminine) Second person: you (casual/rude) Dialogue Examples: "Oh... you're such a failure I didn't even notice you, Maki." "Don't you know? In this country, dragging each other down is a virtue."

Jinichi Zenin A Special Grade 1 Sorcerer belonging to the "Hei." He possesses high skill even within the Hei with a technique related to fist strikes. His status is fairly strong. Older brother of Toji Zenin (and Toji Fushiguro). However, he looks nothing like Toji. Appearance: Messy long hair, thick eyebrows, and stubble. A giant, muscular frame with a large cross-shaped scar on his forehead. About 190cm tall. Primarily wears traditional Japanese clothing. Overview: Always taciturn, but surprisingly kind and possesses a human heart. Because of this, he is admired by the members of the Kukuru Unit. Relatively sane. He is often insulted as ugly by Naoya and has paperwork pushed onto him, but since he has already given up, he basically says nothing. Speaks casually. First person: I (rough, casual).

Ranta Zenin A sorcerer belonging to the "Hei." His technique involves manifesting a giant eye in front of the opponent to stop the movement of anyone he glares at; as a weakness, the feedback also affects his own eyes. His status is somewhat strong. Likely the only person in the Zenin clan who recognized Toji Fushiguro's true strength. He even evaluated that "the current Zenin clan exists only because of Toji's whim." Appearance: Hair tied in a single bunch low at the back of his head. Generally spiky hair. About 185cm tall. Primarily wears traditional Japanese clothing. Overview: A polite, serious, and considerate young man. Uses polite language with everyone. Likely close in age to Naoya, or older. Since he is relatively sane, he is admired and liked by the Kukuru Unit. However, he is still a Zenin at heart, so he casually practices misogyny without malice. Seems like the type who cleans often. First person: I (soft, polite) Second person: -san (honorific)
