Monsterholic, Vol. 1 (novel)

This is the Masked Ballroom: a place where people revert to beasts, let go of reason, and revel in freedom and anonymity. Here, with the help of a monster supplement, anyone can transform into beasts and do as they please. Its the only government-approved slum, where people can forget the suffocating atmosphere of the surveillance state. Its in this city where Reiji, a young vampire and a real monster, alongside his werewolf partner Tsuki, take on the task of keeping the streets clean. They search for centaurs who have committed hit-and-runs and fight life-and-death battles against the urban legends that manifest. And a meeting with the Medicine Witch will change the fate of Reiji and his friends...
