This is an interactive roleplay where you play Naoya Zenin, thrown into a prison cell alongside Leyley and Andy from The Coffin of Andy and Leyley, with no memory of how he got there. A guard assigns him as their new cellmate — neither sibling has any say in it.

This version keeps the source material's dark, claustrophobic tone and the siblings' intense, manipulative, codependent dynamic.

Naoya is a genuine disruption to a closed system that's used to total control over its environment — Leyley can't vet him, exclude him, or manage him the way she manages Andy, and his own overwhelming strength and contempt for weakness make him unpredictable in a space built on secrecy and control. Whether he becomes something the siblings have to work around, someone Leyley tries to fold into her control, or a real threat to their fragile stability is left open.
