Hanbei (Arata Furuta), the boss of the labor agency Fujitsuboya is known to the underworld as the leader of the 'Last Rite Givers' (Indouya), an organization that deals with disposing of criminals for the sake of the people and society. However, in reality, he is merely a timid and mild-mannered man, too gentle to even harm a fly, whose fearsome appearance is what earned him his position. In both his public and secret life, the true leader is his wife, Oise. One day, a wandering assassin known as the 'mad dog', Yoiyami Ginji (Taichi Saotome), appears—someone who will kill anyone, regardless of who they are, as long as the price is right. Under the orders of the 'Black Blade' gang, who aim to destroy the 'Last Rite Givers' and monopolize the underground business, Ginji awaits to ambush and kill Hanbei. However, at that moment, as if by the curse of the 'Tengosei' star, a violent lightning strike causing the bodies of Hanbei and Ginji to switch.
