Kim Min-Kyu, also known as Pontifex Lembrary, is said to have the strongest divine power. He ends up in a new world after fighting a devil and takes over the body of Woo Yeon-Woo, a member of an unsuccessful idol group called Wild Animal. The group is close to breaking up after being together for 3 years. When they perform live on a TV show, Kim, in Woo’s body, messes up the performance by saying he doesn’t know how to dance. But the performance goes viral and the group becomes famous because of Kim’s confident personality. Kim now has to adapt to life as an idol and face challenges dealing with strange religious groups and fighting the devil.
