A supernatural comedy featuring the Prince of Hell and his cat, who fled together from Hell. Upon entering the human world, the Prince’s appearance somehow shifts from tall, dark, and buff to short, light, and skinny. Meanwhile, his cat transforms into a tall, busty woman. The Prince now lives as an ordinary high school student, while the cat serves as the school nurse. In the meantime, the King of Hell dispatches a womanizing vampire, a short-tempered werewolf, and a kind-hearted zombie to retrieve his son.
