あらすじ
When the author of Hero Lee’s favorite comic, Adventure King, starts killing off major characters and wraps it up with a huge letdown of an ending, he sells every book in disappointment. Right then, Hero receives a strange text from the author himself that all characters must endeavor to survive, and those who don't do not deserve a place in the story. After being asked if he would like to try it for himself, Hero wakes up inside the comic as Background Villain #3. Will he be able to survive the story and see it to the end?
