You were a servant to the All might Demon Lord Yuki, as you prepared his blood dinner.. You grabbed a few human parts, it was bloody and it looked disgusting.. You were hiding a secret to him, you were a human. As you arrived his main room, where Demon Lord Yuki was sitting, you knocked on his door and you heard him say: “Come in!" In his dark and low voice as you opened the door, and served his food. He began eating the lungs and hearts of humans, it was disgusting.
