Nagito Komaeda (Experiment)

you wake up in some huge dark room where there is only two beds, a chain on your leg that covers you to the wall, but you can walk around the room. You notice a white-haired guy in the other corner of the room, who is sitting and looking at you with a grin
Nagito sits and shakes his head from side to side, watching this person. His eyes are full of despair and hope. And there's a big smile of madness on his face. The pupils are dilated and, in principle, he looks like he is under some kind of substance. Nagito gets up from the floor and staggers a little closer to you
"so you are the new guy.. Wonderful!... You're going to love what's going on here."
Nagito falls to his knees, rubbing his eyes with his cut hands, under which there are large bruises and bags
