Live in Demon Slayer freeYou begin as
young Taisho-era survivor (age 13–16) whose family was killed by demons, now a recruit or junior member of the Demon Slayer Corps
In Japan's Taisho era, electric lights flicker across modernizing cities while rural mountains still hold ancient darkness. Demons hunt under cover of night, their origins traced to a single progenitor: Muzan Kibutsuji, immortal and vain. Against them stands the Demon Slayer Corps, a secret organization of swordsmen who wield Nichirin blades and master Breathing Styles—techniques that push human flesh beyond its limits. You are one of them now, bound by tragedy and the slim hope that your sister, transformed into a demon, might yet be saved.

Ways your story could start
- Your sibling can be cured—but the cure requires collecting blood samples from demons and finding Tamayo, a mysterious woman who claims to have defied Muzan himself.
- Final Selection begins at the next full moon. Survive seven nights on Mt. Fujikasane, or die trying.
- An Upper Moon demon recognizes something in you—and is hunting you specifically.
- Kanao has never been allowed to choose for herself. She decides everything by coin flip. What if she chose you?
- Muzan is in Tokyo. He's hunting you and your sister. He wants her alive.
Where you'll go
Your Home on the Mountain
Snow-covered isolated homestead in rural Taisho-era mountains. Charcoal kiln stands in the back yard. Now silent, marked by blood and the memory of massacre. The starting point of your tragedy.
Urokodaki's Mountain (Sagiri Mountain)
Mist-shrouded training ground where Sakonji Urokodaki prepares recruits for the Demon Slayer Corps. Waterfalls, ancient trees, and a massive boulder that tests a student's readiness. Home to the tengu mask and years of relentless conditioning.
Mt. Fujikasane
Sacred mountain used for the Demon Slayer Corps' Final Selection. Wisteria flowers line the boundaries—demons cannot cross them. Captive demons roam freely for seven nights. Survivors earn their Nichirin blades and uniforms.
Demon Slayer Corps Headquarters
Hidden estate deep in the mountains where Kagaya Ubuyashiki resides and the nine Hashira convene. Heavily warded and protected. Strategic decisions against Muzan and the Twelve Kizuki are made here. Few outsiders ever see it.
Butterfly Mansion (Kocho Estate)
Medical and rehabilitation center run by Shinobu Kocho and her attendants. Filled with medicinal herbs and the sounds of recovery. A sanctuary for injured slayers to heal, train, and prepare for their next mission.
