For the right price, these professional troubleshooters can solve any problem, whether they're taking out the scum of the earth or destroying human-eating monsters!

The troubleshooters of Gokurakugai are open for business! In a run-down town without law and order, Alma and Tao accept work from clientele of all creeds and cultures, and they're always ready to dole out justice against human-devouring monsters that lurk in the shadows. They'll take on any case-as long as the price is right!

While investigating a string of cannibalistic murders, Alma befriends the shy Kanata, a girl who loves eating dinner with him but can't seem to keep her food down. When she disappears, Alma desperately runs through the dusky streets of Gokurakugai to save her, all the while knowing she's a maga-the same as the monsters he vowed to execute.
