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.
En's murder sends his gang into chaos as Shin and Noi attempt to locate his killer's whereabouts. Meanwhile, Nikaido and Kawajiri explore her magical abilities and how they might relate to the search for Caiman. And the Cross-Eyes continue their quest to see their boss—unaware of his role in En's death, or that their path is taking them straight into danger themselves. A bloody battle royale awaits.
