Once upon a time, a human witch and a demon king fell in love. They were married, and they had a son, Laharl. Laharl got sick, and his mother sacrificed her life to save him. Then Laharl, ungrateful boy that he is, decided he no longer believed in love, making his mother's sacrifice worthless! The~end~!
