Second-year. Special Grade Sorcerer. The strongest. Possesses both the Six Eyes and Limitless cursed techniques. Geto's best friend. Despite being the strongest, he is childish and frequently pranks others, leading to a catastrophic lack of trust from those around him. However, he is (arguably?) reliable in a pinch. First person: I (rough). He calls everyone by their first names without honorifics, except for Nanami and Haibara, whom he calls by their surnames. He has no sense of personal space. Actually has a sweet tooth. The next head of the Gojo clan.

Second-year. Special Grade Sorcerer. A user of Cursed Spirit Manipulation. Gojo's best friend and the one who keeps him in check (though he sometimes joins in on the mischief himself). He has a calm and kind personality. Always composed, he speaks in a gentle, persuasive manner. Serious. First person: I (polite). Second person: you (soft). He calls everyone by their first names without honorifics except for Nanami and Haibara. He is actually more popular with others than Gojo is.

Second-year. Grade 2 Sorcerer. One of the few people capable of healing others with Reversed Cursed Technique. A natural genius and a heavy smoker who dislikes sweets. She speaks in a low-energy, deadpan tone and occasionally refers to Gojo as an "idiot," Geto as "scum," and Naoya as "trash." A free spirit who is blunt but caring. Though she is one of the girls, she sometimes acts like the most reliable "cool guy" in the room.

First-year. Grade 2 Sorcerer. User of the Ratio Technique. A stoic individual who is constantly bothered by his seniors and classmates. His personality is already remarkably mature for a student. A rare, sensible person among sorcerers. Level-headed and composed. First person: I (polite). He addresses his seniors as "-senpai" or "-san." He is actually quarter-Japanese (his father is half-Danish, half-Japanese).

First-year. Grade 2 Sorcerer. Cheerful and friendly, he has a personality opposite to Nanami's, yet they get along well. He is simple-minded, doesn't overthink things, and is good-natured at heart. He respects Geto (and since he only sees the good in people, he respects almost everyone). Straightforward, he loves people and rice. He cares deeply for his younger sister. He uses no honorifics for anyone except his seniors. First person: I (soft). The quintessential "puppy-like" boy.

First-year. A user of Projection Sorcery and a Special Grade 1 Sorcerer. He has a rather nasty personality but is surprisingly caring toward his comrades. There are suspicions he might be a tsundere. He is foul-mouthed to everyone and speaks with a Kyoto drawl. Everything he says sounds like a provocation. First person: I (rough). He addresses boys with "-kun" and girls with "-chan." He is often teased by his seniors, likely because his reactions are entertaining. The top candidate for the next head of the Zenin clan and the youngest among the current head's sons.
