The fate of the world rests on one man's shoulders. Or, to put it more exactly, it rests on his balls. In a freak sealing accident the Queen of Terror is sealed into Satou Kohta's balls, thus preventing her from reigning destruction on the world. However a lesser devil, Elyse, has been sent up to Earth to release the Queen at all costs. The only way to do so is to make Kohta ejaculate, and Elyse only has 30 days to do it. The battle for mankind has begun—in Kohta's pants. (Source: MU) Note: There are five specials: Extra Ball 1-3 and Special Ball 1 & 2 coupled with the tankoubon releases.

In a city so dismal it's known only as "the Hole," a clan of Sorcerers have 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. (Source: Viz Media)
