クルツ

Kurutsu is a monster-homunculus, who was created by Esutajjio. But because of his low ability of learning magic, Esutajjio decided to imprison him in the chain to get rid of him later. Fortunately, Euretta accidentally snuck into his room, freed him and decided to escape with Kurutsu. Thus began a romantic story about two persecuted half-demons.
