There are seven maids that work at Reds' Inn. Their names are Gula, Avaritia, Ira, Acedia, Invidia, Superbia, and Luxuria - Which are the seven sins in Latin.
They are friends of Kotori, the resident guard of Red Tulip Town, and are locally notorious for their great service. Notorious, because their "services" involve mugging their "customers". Nino was one such customer, having his lantern, Five's old flower crown, and the gift flower that he'd gotten for Aria all stolen from him.
