A series of three full-length OVAs, each telling a different story centered on a particular Yakin Byoutou heroine. The first story is about Ren Nanase, who has heard rumors that one of her teachers is a rapist, and she does exactly what any good citizen would do. Unfortunately, from that moment on, everything goes downhill, and she finds herself his sex slave undergoing an accelerated course of debauchery… But, can there really be anything light in all this perversion, too? The second, Kazama Mana’s story – She is interning at a sanitarium as a nurse-intern. Mana wants to be an angel in white for her charges. But Ayumu Mizukawa, a mental patient whose days are numbered, tells her that there are no angels, and begins to turn her into his sex slave… The third story is about Yagami Yuu, a nurse who takes her job very seriously and lets her hopeless patients do whatever they want with them, and each time in more and more perverted and dirty ways…
