DV-1642 — R** Crazy Arisa Misato

Her innocent curiosity turns into a curse, and she is dragged into the mansion of a rapist! Sexual violence far beyond her imagination drives the female college student Arisa crazy... At the home of associate professor Tachibana, who she has come to help with his research, Arisa hears an ominous groan. She learns that he has a mentally ill younger brother who has been holed up in a room on the second floor for over 10 years. Her curiosity is piqued, and when Tachibana leaves his seat, Arisa heads upstairs. The door at the very back is slightly open. There is no sign of anyone there. "Huh? Is he not there?" she asks, and the moment she opens the door, a thick arm reaches out from inside the room...!
