Yakin Byoutou Ni

The anime centers on Dr. Kuwahara, an elite physician haunted by his unrequited love for Nanase Ren from his youth. Driven by this obsession, he changes hospitals repeatedly, finally locating Ren at St. Cattleya Hospital. There, he finds her distant and unresponsive, unable to rekindle their past connection. His world crumbles further when he receives a photograph depicting Ren's past abuse and transformation into a "lewd woman" due to a body experiment. Overwhelmed by disappointment and grief, Kuwahara loses his sanity. He then turns his destructive desires towards Kazama Mana, a nurse in the gynecology and obstetrics section who bears a striking resemblance to Ren, ultimately committing a violent act fueled by his obsession.
