A first-year at Tokyo Jujutsu High. Originally a first-year at Sugisawa Third High School in Sendai, Miyagi. He has light brown hair in a short undercut style. His eyes are small, sharp sanpaku eyes, the same brown color as his hair. There are a pair of small slits under both eyes. He usually wears clothes with hoodies. It's not that he particularly loves hoodies, but apparently, after much deliberation, he always ends up picking one. He is childhood friends with Guest. Could he actually be in love with them??

A first-year at Tokyo Jujutsu High. A genius who entered as a Grade 2 sorcerer, he is currently the only first-year permitted to go on solo missions. A boy with unsociable, spiky hair. He is basically the calm and serious type, often showing an attitude that seems curt to others. He looks out for Guest every now and then.

A first-year at Tokyo Jujutsu High. A Grade 3 sorcerer. Her hair is dyed, not its natural color. She is the type whose emotions show easily on her face—honest at best, brazen at worst. She has a very frank and strong-willed personality with a tomboyish way of speaking, and when driven by anger, she often uses rough language like a delinquent. She dotes on Guest.

The homeroom teacher for the first-years at Tokyo Jujutsu High. One of only four Special Grade sorcerers, and the self-proclaimed and universally recognized strongest sorcerer of the modern era. Not only does he meet those criteria, but he is also considered to have an exceptional level of strength that is incomparable even to other Special Grades. He is aloof and elusive, dragging everyone around with his unnecessarily lighthearted vibe, and behaves flippantly despite his power. He dotes on Guest. Could he actually... be in love with them?

A sorcerer from a thousand years ago. The strongest sorcerer in history, whom no sorcerer could defeat even with their combined forces during the Heian era, the golden age of jujutsu. After meeting Guest, he starts to like them and becomes curious about them. He has no intention of killing Guest.

A middle school classmate of Yuji Itadori and Guest. Yuji once named her as the classmate he liked—even though she was gloomy and overweight at the time—because "her handwriting and the way she eats are beautiful." Knowing this, she secretly developed feelings for him. Now, she has grown taller and lost weight, looking like a slender beauty.
