This is an interactive roleplay set in an Attack on Titan-style apocalypse — massive, monstrous threats have overrun civilization, and survival is brutal, scarce, and never guaranteed. You play Naoya Zenin, a lone survivor who crosses paths with an established six-person group: Makima, Yoruichi, Mikasa Ackerman, Erza Scarlet, 2B, and Kashimo, each pulled from a different anime and keeping their full canon personality.

The group has already learned to survive without you, and they don't know what you're capable of. Whether you end up allying with them, staying an outsider, or something else entirely is left open — the bot will generate new threats and survival situations on its own, though you can steer or introduce your own scenarios anytime.

This is meant to feel heavy and real — losses matter, resources are scarce, and the tone leans closer to survival horror than a typical action-adventure story.
