Miyamori Tatsuya was spending his life in idleness, doing shady jobs and getting involved with dubious women. "I want you to infiltrate a certain care facility and expose what's going on inside." Such was the request a certain mysterious girl, Yuu, approached him with. Captivated by her, Tatsuya accepts - but the facility in question appears to be much more suspicious than he had imagined. The shady owner. Dark pasts looming in the corners. Sex with the female convalescents. The more time Tatsuya spends inside as a live-in care volunteer, the more his mental state deteriorates. Between flashbacks of the past and strange nightmares of a far-off land, will he be able to leave the facility unharmed? And just what is Yuu's goal? [From The Official site]
