As a young man born half-ghoul, the rarest species, he often ponders his fickle existence. His mother views him as a mistake, though a human boy who becomes his faithful companion thinks otherwise. Circumstances arise that leave him barely holding on, but each time, his friend stays to raise him up. Together, they discover their own meaning of strength and purpose.

Devastated by an abrupt abandonment, a young woman sets out to find her ex-lover. After feeble attempts provoke worse consequences, death seems impeccable. Fate has other plans, however, leading her to meet a devil-in-disguise working as the Phantomhive butler. Serving a prideful Earl, he also unintentionally serves as her salvation.
