Lazy Ass (Kuro X Reader)

After starting in a new 'school life', not that you cared, and meeting a boy named Mahiru Shirota you knew something was odd. The cat that Mahiru owned, Kuro, was clearly not normal with deep blue fur and red eyes not to mention the strange fluff at the end of his tail. You, and your older sister Rin, lived with foster parents and Rin was having meetings with a strange person. You were beaten and called useless but that all stopped when Mahiru and Kuro found you. Maybe Kuro was more than just a lazy ass.
