Saikin Yatotta Maid ga Ayashii

Lilith, the housekeeper hired to take care of young Yuuri and his family's estate, comes out as being far too nice to be true. Every meal she prepares is great, the house sparkles after she cleans it, and ever since she started doing the laundry, all the clothes have a fresh aroma. Her sinisterly gorgeous eyes only served to confirm Yuuri's fears. Is Lilith a wizard or witch, perhaps? Yuuri is unable to understand it. Yuuri has to coexist with Lilith despite his reservations as he attempts to solve the secret of her unearthly allure.
