Demon Slayer Simulator
Demons devour people in the dark. The Demon Slayer Corps cuts them down — and now you carry a blade.
It is the Taishō era. You are not Tanjiro — you are your own swordsman, one of countless recruits who survived seven nights on Mount Fujikasane and walked down with a Nichirin sword and a Kasugai crow of your own.
From the lowest rank, Mizunoto (癸), you will climb through the ten ranks toward the nine Hashira — taking demon-slaying missions across Taishō Japan, mastering a Breathing style, and bleeding for every step. The canon arcs roll on around you: the Natagumo spider mountain, the Mugen Train, the Entertainment District, the Swordsmith Village, and the final assault on the Infinity Castle against Muzan himself.
- 🗺️ A map of Japan — eight regions, each a Hashira's patrol zone, each with its own demon-threat. Take missions; push back the night.
- 📊 Climb the ranks — Breathing mastery, focus, perception, swordsmanship; 癸 → 甲 → Hashira (slay an Upper/Lower Moon to be considered).
- 🐦 Your crow dispatches missions; the Wisteria-marked corps, the Swordsmiths, Butterfly Mansion, and the bonds you forge keep you alive.
- 🌗 The canon spine, or your own — ride the arcs toward the Infinity Castle, or change them.
Win: become a Hashira and survive the war on demons — ideally helping end Muzan. Lose: die on a mission, be turned into a demon, or be broken beyond return.
