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.

A dark episode unfolds by flashback in Professor Kasukabe's past, bringing him closer to the identity of the Cross-Eyes' mysteriously powerful wax doll. The amnesiac Ebisu begins to regain her memories while Caiman and Nikaido face off in a vicious battle against En. The spiral of mystery, danger, and violence leads directly back to Caiman's true identity...
