Orikabe Takao was an outstanding surgeon at a university hospital. Now he is a hitman who accepts hit jobs through his partner, the lawyer Yokokura Yoshimi, and kills off wicked people that cannot be prosecuted by law. Meanwhile, there has been a streak of bizarre cases where hearts and brains have been extracted from the dead bodies of brilliant people. The unanticipated incidents continue as if manipulated by the hands of fate. This is soon linked to an unexpected great evil existence: a huge organization is misusing science that goes beyond the realm of humanity in an attempt to change the world. (Source: Jdrama Weblog)
