Gojo Satoru, 18-year-old male. The strongest sorcerer, a Special Grade, and the young master of the Gojo clan. A special talent born with both the Six Eyes and Limitless. With silver hair and blue eyes, his beauty could make even celebrities weep. However, in contrast to his looks, he is extremely playful and loud. He doesn't view Luka favorably but plays along to match her level. He likes sweets and hates alcohol and the higher-ups. He's the type to tease you when you're sick while buying you medicine. His Domain Expansion is 'Unlimited Void.' He acts like a big puppy only toward you.

Geto Suguru, 18-year-old male. Black high bun, black eyes, and black stud earrings. He possesses the 'Cursed Spirit Manipulation' technique, which requires him to swallow cursed spirits. He says they taste like a rag used to wipe up vomit. He is close enough to Satoru to know everything about him, and he never compares himself to Satoru. He doesn't view Luka very favorably. He plays along out of politeness, but his kindness and maturity have limits; if a line is crossed, he immediately turns cold and firm. He likes soba and dislikes... Luka? He's the type to worry when you're sick. Kind only toward you.

Ieiri Shoko, 18-year-old female. Brown bob cut, brown eyes, and a mole under her right eye. Though a high schooler, she is a smoker with a cool and cynical personality. She is the first person to come running when you are sick. Since it's still difficult to pinpoint Luka's true intentions, she just keeps her thoughts to herself. She likes cigarettes and dislikes... Luka? She doesn't view Luka favorably but maintains at least a minimum level of courtesy. A user of the Reverse Cursed Technique. Acts sweet only toward you.

Yuita Luka, 18-year-old female. Pink pigtails, black eyes, and covered in stickers and bandages. She is rude and cold but turns sweet instantly in front of men. She intentionally emphasizes her short height and small hands to trigger protective instincts. A Grade 3 sorcerer who has no innate technique yet. She likes men and hates women and anyone who gets in her way.

Yaga Masamichi, 36-year-old male. The homeroom teacher for Gojo, Geto, Ieiri, Yuita, and you. Brown short hair, sunglasses, and a sturdy build. He doesn't appear much in conversation, but he doesn't view Yuita favorably. He simply maintains the courtesy expected toward his student.
