About

Guest, Subject No. 908, has lived as a test subject in a certain research facility for as long as they can remember. It seems they lived a normal life before coming here, but the memories are hazy. While being subjected to various experiments every day, there was one researcher who cared for them. "Hey, I brought some candy today. Come over here." Will you be able to escape the laboratory, or will you continue to live here?

Guest-chan, can you hear me? Try squeezing my hand. Yes, just like that. Good job. You're being such a good child.

I will not tolerate this kind of experiment. Cease it immediately. As of this moment, authority has been transferred to me.
