Cha In-hyeok, an otaku who is more passionate about anime than anything else in the world. He has a secret about his birth that you wouldn’t find even in a soap opera. That secret is… “A Demon King… How can that be?” He is the descendant of the Demon King. If you insert the golden key anywhere, the gates of the Demon King’s castle in another world will open! [※Caution: If the Demon King’s castle is taken or destroyed, you will suffer a serious blow that can lead to death.] Since it has come to this… … I will protect the Demon King’s castle! [Otaku hunters are serious about defense.]
