Xiomyna is struggling to provide for his family. When he's somehow transported to another world, the only thing he remembers of his past life is the little key that will help him return.
When he hears of a woman who's husband was possessed by a key obsessed ghost, he enlists the help of part time pirate Coco and half-goddess Yasui Maiko to undergo the dangerous transformation to become a ghost. But little does he know that it has fatal consequences.
It's a race against time to find the ghost with his key before he's separated from his mortal body for good. He is faced with a choice - save his blood family at home or his found family in Tneva?
