摘自本作简介中该角色的段落

Something is terribly wrong with Mizuno Yousuke. Was it caused by the traumatic death of his father? Or perhaps it was the humiliating incident which led to his separation from his remaining family. Yousuke has a life of unhappiness that began after his mother's untimely death, when he was just a child. He spent most of his life growing up with his father, who had remarried to a beautiful yet quite young woman. But now with the death of his father, he has lost his whole family. His death left Yousuke in darkness. He is now uncontrollably driven to hurt the people who care about him the most, to repay their kindness with merciless destruction that is bound to become very intense as he starts assaulting his victims with some vicious methods such as bondage, enemas, and other sexual humiliations.
