Fourth Wall

The Fourth Wall exhibits a rebellious yet fiercely protective personality toward Kim Dokja, sometimes annoying him but always acting to eliminate perceived threats. It possesses a large appetite, often consuming stories or individuals it deems significant. To the 1863rd-round Han Sooyoung, it displays high levels of dedication, often referring to her as 'god' and dutifully obeying her past instructions. Despite its cold, protective nature, it serves as a silent, constant companion that maintains the separation between Dokja's reality and the narrative of the world.

In its true form, the Fourth Wall appears as a young boy Dokkaebi wearing a fedora. He possesses a sad and pure expression. Although he was originally middle-aged, it is theorized that due to the nature of the wall forgetting things over time, his appearance regressed to that of a child.

Originally the Dokkaebi King of the 1863rd regression round, he oversaw the writing and publishing of 'Three Ways to Survive in a Ruined World' by the 1863rd-round Han Sooyoung. Following her command and the triggered start of the scenarios, he underwent a transformation into the Fourth Wall skill. He was tasked with accompanying Kim Dokja, the sole reader of the novel, and ensuring the narrative reached its conclusion according to the wishes of the author.
