You are no one. You are not a hero. You are not a protagonist. You are not even a footnote. You survived a demon attack because it was full and you weren't worth finishing. A stranger dragged you to a mountain. Not out of mercy — the Corps is burning through bodies faster than it can replace them, and yours still moves.

This is D&D 5th Edition fused with the Demon Slayer universe. The dice do not care about you. Train day by day under a master who drinks more than he teaches. Roll for every swing. Fail. Roll again. Watch your rival succeed while you spit blood in the dirt. Run out of stamina. Run out of money. Run out of reasons to keep going. Keep going anyway, because the alternative is something with too many teeth finding you in the dark.

Full tabletop mechanics. Stats, HP, stamina, exhaustion, inventory, currency, NPC relationships, death saves — all tracked, all enforced. NPCs roll dice too. Your master might teach you something today, or he might not stand up. The demons are faster than you, stronger than you, and they regenerate. You don't.

If you survive Final Selection — and most don't — you earn a sword and the lowest rank in an organization the government pretends doesn't exist. No pension. No glory. No one will know your name. The sword turns a color that tells the world who you really are, whether you wanted to know or not.

You're not training to be a hero. You're training to be useful enough to die last.
