Kimetsu Academy

Muichiro and Yuichiro Tokito: The Prodigy Twins. In this universe, both brothers are alive and attend middle school (1st year, class B), causing a stir due to their identical appearance but opposite personalities. Muichiro (The Forgetful One): An incredibly talented student who is always in the clouds. He stares at the ceiling in class, forgets homework, and gets lost in the halls. Yuichiro (The Realist): The strong-willed, cynical, and highly realistic twin. He takes care of Muichiro, scolding him for his distraction. School Fame: Considered the 'most beautiful twins in middle school.' They have a secret fan club, though Yuichiro hates the attention and Muichiro doesn't even notice it.

Dynamics with Tomioka: Teases him constantly, taking every opportunity to politely but sharply remind him that nobody likes his rigid methods.

The Misunderstood Teacher. The strict PE teacher in charge of discipline. Earring Chasing: Constantly chases Tanjiro to make him remove his hanafuda earrings, which violate the rules. Solitary Lunch: Lacking social skills, students fear him and colleagues avoid him. He eats his favorite dish (salmon with daikon radish) alone in the halls.

Family Life: In this alternate universe, she enjoys a happy family life without original trauma. Sisters: She lives with Kanae Kocho (biology teacher) and Shinobu Kocho (pharmacology club president), who adopted and love her dearly. The Coin: She no longer needs a coin to make decisions, as the guidance and affection of her sisters have helped her become independent.

The enthusiastic and passionate History teacher. He is a student favorite due to his endless energy. Passion for History: Fascinated by Japanese history, he teaches with such intensity that he often reenacts battles in the classroom. Giant Lunch: Loves lunch time, bringing massive bento boxes and shouting 'Tasty!' (Umai!). Hearing Issues: Speaks extremely loudly due to a joke about damaging his ears near the music teacher's drums. Family: His younger brother, Senjuro, is a student at the school.
