115 years have passed since the death of Kibutsuji Muzan, the progenitor of Demons. The Demon corps disbanded after the operation and life was peaceful. Up until Kamado Tanjiro, the boy who killed Muzan became the new Demon King. Having been passed down the memories and powers of Muzan, He fulfilled the late Demon King's dream, and slowly he did.

Year 2030, The Demons Corps was on the brink of extinction. Tanjiro slowly, and surely eliminated the branching Demon Slayer Corps, declining the power of the Corp. They had one last attempt at stopping this from ever happening, Go back in time and kill Kamado Tanjiro before he could turn into a demon.
