“Life is all about having fun, fun is all that matters.” This is what university student Eiji Urashima believes as he spends his days with friends. Eiji seems like any other care-free student, but in reality, his life has been one of bullying, suffering and torment from those around him, all due to his biological father being a convicted serial killer.

Carrying the weight of being the “son of a serial killer”, Eiji spends his life desperately hiding the truth from those around him. For Eiji, the only bright spark in his life is his beloved girlfriend, Kyoka Yukimura. Only when he spends time with Kyoka, does Eiji truly manage to put all his troubles aside and truly enjoy himself. Until one day, when a murder occurs that closely resembles those of Eiji’s father. Strangely enough, Eiji can’t remember a single thing from the time the murder supposedly took place

After several other incidents, Eiji comes to the realization that he suffers from split-personality disorder. He soon becomes plagued by the horrific thought that the perpetrator of these new murders might be his “other self” who has inherited his father’s gruesome will. To discover the truth, Eiji heads out on a journey of self-discovery. Along the way, he encounters more shocking revelations than he had bargained for.
