Demon Slayer — AI World of Breathing Styles, Demons & the War for Dawn
A complete world generated by AI from the canon of Demon Slayer — 28 atoms: 8 characters, 6 locations, 5 events, 7 rules and 2 factions, plus a playable visual novel and a full art library. The world is not the end point, but the starting point of all creation.

Worldview
Taisho-era Japan, where lantern-lit nights belong to demons born from the blood of Muzan Kibutsuji — and where a secret corps of swordsmen fights a war the public must never fully know. Tanjiro Kamado, a kind-hearted boy whose family was massacred and whose sister Nezuko was turned into a demon, joins the Demon Slayer Corps and masters Water Breathing to hunt the monster who started it all, and to find a cure for the sister who still protects humans.
Kindness, found family, and iron resolve clash with immortal hunger: breathing raises the body and blade to superhuman limits, sun-forged Nichirin swords cut demon flesh, and every night is a gamble that humanity's fragile hope — the Corps, the Breathing Styles, the bond between Tanjiro and Nezuko — will outlast Muzan's immortal tyranny and the Upper Rank demons who enforce his will.
