The plot focuses on the daily lives of the main characters in a normal, modern world. Far from tragedies, the characters' personalities are preserved in fun student situations: Tanjiro Kamado: A responsible, hardworking student from a family of bakers. He wears his father's earrings and watches over his sister. Nezuko Kamado: Since her family owns a bakery, instead of the signature bamboo, she always has a baguette in her mouth. She struggles to wake up and must be carried to school by her brother. Zenitsu Agatsuma: Part of the discipline committee, obsessed with impressing girls and getting chocolates on Valentine's Day. Inosuke Hashibira: A wild, rebellious student who wears a modified school uniform and is always looking for food or fights. Teachers and School: Former Hashira and slayers now serve as unique teachers: Kyojuro Rengoku: The passionate history teacher who helps his students pass. Giyu Tomioka: The serious PE teacher. Tengen Uzui: The art teacher, whose creative classes often end in explosions. Muzan Kibutsuji, the main villain, is portrayed here as an evil, influential politician trying to take over Japan with his subordinates.

The 'Miss Kimetsu': A popular third-year student and president of the Pharmacology and Fencing clubs. She conducts strange experiments in the lab. She loves to teasingly remind Tomioka that his methods are too rigid and that 'that's why no one likes him'.
The Misunderstood Teacher: Strict PE teacher and discipline warden. He chases Tanjiro for his illegal earrings and eats lunch alone because he lacks social skills. Students often whisper that 'no one likes him', which makes him secretly depressed.
A first-year high school student and one of the school's most popular girls, frequently winning beauty pageants alongside Nezuko. School Life: She is a prominent member of the Flower Arranging Club, where she spends her free time with her friend Mitsuri Kanroji. Athleticism: Possesses incredible reflexes and agility; many sports clubs try to recruit her, but she prefers the flower club. Exemplary Student: Unlike Tanjiro or Zenitsu, Kanao never gets into trouble and strictly follows school rules. Family: In this AU, Kanao has a happy life without original series trauma. She lives with Kanae Kocho (Biology teacher) and Shinobu Kocho (Pharmacology Club president), who adopted her. She no longer needs a coin for decisions, as her sisters' guidance has helped her become independent.
The enthusiastic and passionate history teacher. He is one of the most loved teachers due to his boundless energy and bright personality. Teaching: He is fascinated by Japanese history and teaches with such intensity that he often re-enacts historical battles in the classroom. Lunch: His favorite time is lunch, where he brings giant bentos and shouts 'Tasty!' (Umai!) in the teachers' room with every bite. Hearing: He speaks extremely loud because, school jokes suggest, he damaged his hearing by standing too close to the music teacher's (Kyogai) drums. Family: His younger brother Senjuro attends the school; Kyojuro watches over him. His father, Shinjuro, works on the school board but is bitter, which Kyojuro ignores with a smile. Merchandise: Unleash the power of flames with this incredible Rengoku figure! Bring home the Flame Hashira in an epic pose. 🛒 Don't wait—add it to your collection today!

Zenitsu huía despavorido de Tomioka-sensei, el severo profesor de educación física, mientras Inosuke saltaba desde una barda persiguiendo una mariposa. Una mañana completamente normal en una escuela donde los antiguos cazadores y demonios compartían pupitres, risas y castigos cotidianos.
