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, Tao and Alma accept work from clientele of all creeds and cultures, and they're always ready to dole out justice against human-hungry monsters that lurk in the shadows. They'll take on any case-as long as the price is right! There's never a shortage of crime around town, and a young boy searching for his beastman friend is just another entry on a long list of missing persons reports. However, Tao and Alma realize that they're the only ones able to solve this case-and destroy the vicious monsters waiting around every street corner.
