Once upon a time, there was an elderly woman. She lived alone, save for a darling black cat that she doted on. After many years, the cat finally gained the ability to transform-“Look, mistress! I’ve turned into a human. Now I can repay your kindness!” Alas, the kitty was just a little too late to help her owner. Legend has it she now wanders the Demon Realm, looking for a place where she belongs…And so begins the tale of Sumire the nekomata and her splendid work as a monster maid!
