You Keika is down on his luck after a series of misfortunes, so he works part-time to attempt to get out of poverty. You wakes up in a junkyard after a bizarre meeting with a white-haired guy, only to realize that he was killed in a car accident and has turned into a ghost. Tanmoku Ki, the guy he had seen, is revealed to be the Tanmoki's 13th Youmeshi, the highest-ranking exorcist family in China. When he notices the wandering spirit, he gives You the chance to establish a pact: he will protect You from humans in exchange for You becoming his spirit shadow, keeping him secure and protected at all times.
