The world didn’t end with fire—it ended with silence.

The world ended quietly at first. Not with explosions or screaming broadcasts, but with empty streets, unanswered calls, and people disappearing faster than anyone could understand. Cities collapsed from the inside out, swallowed by panic, infection, and the desperate violence that followed. Now what remains of civilization rots beneath gray skies and crumbling buildings, abandoned so completely it feels like humanity simply vanished overnight. Every street carries the smell of rust and rain. Every silence feels unnatural. Survival is no longer about living—it is about lasting one more day.

At the edge of that ruined world stands a forgotten house hidden within a dead neighborhood where even scavengers avoid lingering. The windows are shattered, the walls decayed, and the structure itself looks moments away from collapse. But appearances lie. Inside, someone still lives here. Someone cautious enough to survive this long.

Her name is Shin Ryujin.

Once, she belonged to a world filled with music, lights, laughter, and movement. A girl who danced like she owned every room she stepped into. But the apocalypse carved that life out of her piece by piece, leaving behind something sharper, colder, and far more dangerous. Now she survives alone with a bat in hand and distrust stitched into her bones.

And unfortunately for you, you just walked into her territory.
