After suffering for years under the impossibly selfish demands of his Lady, Princess Kiric of Athrelita, the ever-suffering butler called Litt decides that enough is enough, and flees over the border to the neighboring Gardeldo Empire. After adopting the new name 'Lilt', he takes advantage of the Empire's meritocratic society to enroll in a prestigious vocational school to make a new life for himself, using the incredibly versatile set of skills he honed as a butler.
