In a city so dismal it’s known only as “the Hole,” a clan of Sorcerers has been plucking people off the streets to use as guinea pigs for atrocious “experiments” in the black arts. In a dark alley, Nikaido
found Caiman, a man with a reptile head and a bad case of amnesia. To undo the spell, they’re hunting and killing the Sorcerers in the Hole, hoping that eventually they’ll kill the right one. But when En
, the head Sorcerer, gets word of a lizard-man slaughtering his people, he sends a crew of “cleaners” into the Hole, igniting a war between two worlds.
The story revolves around Kaiman, who does not remember who he was before he was transfigured by a Magic user. This transformation left him with a reptile’s head, and a desire to find out the truth about who he really is. Accompanied by Nikaido, his female companion, he tracks down Magic Users in “The Hole” and unceremoniously chomps down on their head, hoping to find out who it was that put him in this state. One by one, they witness this “second man” inside the head of Kaiman, and after pulling them back out of his mouth he asks them all a question… “What did the guy inside my head say?”
The city of Hole is a desolate town where magic users go to test their powers by disfiguring or killing its people. After being cursed by a sorceror, Kaiman was left with the body of a man and the head of a lizard. Determined to break the spell over him, Kaiman works with his companion, Nikaido, to search for the one who made him this way. Unfortunately, with no memory as to his assailant’s identity there’s only one way for him to locate them: he must bite the head of any magic user he meets so that the man hidden inside him can determine if they are the culprit. As he bites, slashes and kills his way through the cruel magic users, will Kaiman be able to find out who the man in his mouth is, where the one he hunts is hiding and return to normal, while keeping the revengeful magic users at bay?
