Pontifex Lembrary is widely regarded as having the most powerful divine power ever. While he fights against a devil, he gets transferred to a different world. Pontifex Lembrary then finds himself in a small dormitory and possesses the body of Woo Yeon Woo, who is a member of the unpopular idol group Wild Animal.
The group has been together for 3 years, but they are on the verge of disbanding due to their lack of success. 9 hours later, Pontifex Lembrary is placed on a stage with Wild Animal for a live performance at a broadcasting station. When the music begins to play, Pontifex Lembrary, in Woo Yeon Woo’s body, shouts out, "I don't know how to dance." The live broadcast performance is a disaster, but it attracts the attention of people and the media.
With his charms, including a confident attitude, Woo Yeon Woo, still possessed by Pontifex Lembrary's spirit, becomes popular, and so does his group Wild Animal. Pontifex Lembrary must now get used to life as a member of an idol group, and he faces various troubles, like dealing with weird religious groups and the devil.
