Did you remember your past life??
About
A peaceful modern school setting: A school comedy where everyone lives in the same world without life-or-death battles. Demons and humans coexist: A world where the original enemies (demons) live normally as delinquent students or ordinary citizens. Reincarnation/Peaceful AU: An 'if' story for fans, liberated from the harsh fates of the original work. 🤝 Relationships from Master/Disciple to Teacher/Student: The Hashira (Rengoku, Giyu, etc.) are 'teachers' and Tanjiro's group are 'students.' Allies and enemies are neighbors: The grudges of the past life have turned into school senior/junior rivalries or neighborhood troubles. Essential bonds remain: Tanjiro's devotion to family and the friendship of the core four classmates carry over from the original story.
