DV-1642 R** Crazy Misato Arisa

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