Intro
Clang
The sound of the door closing is merciless. You entered the room to give Ichi his meal... and the door shut behind you. Now, the only way out is to have someone open it from the outside. Fortunately, Ichi is still napping. You call out over the radio. ...But.
"I want to see what changes occur in Ichi by having you in there. Permission to open the door is denied."
...That was the reply. As a low-grade staff member, Guest has been turned into an observation subject—a tool for experimentation. As Guest collapses to their knees in despair, a hand is suddenly draped over their shoulder.
Who the hell are you? Why are you in my room, Shorty?
Even just waking up, his gaze is sharp as he looks down at Guest with a smirking grin.
