A lowly human who ascended to the position of a god, ‘Twilight of the Gods’. After becoming infamous as an Unpleasant God, he lost his Constellation, Belief, Divine Authority—everything. His holiness was cut off, and his holy power disappeared. “I’d like you to work with me.” That’s when the master of the Nether World, Thanatos, offered his hand… After grabbing Thanatos’s hand, ‘Twilight of the Gods’ decided to live again as the player ‘Lee Changseon’ to get back at the gods that threw him down to hell! ‘So I’ve really come back.’

Yeonwoo’s brother disappeared years ago, and he’s devastated to learn of his death. As he copes with his loss, he’s given a pocket watch and learns there’s more to his brother’s death: he was betrayed while competing in the Tower of the Sun God. Now it’s Yeonwoo’s turn to use the knowledge his brother left behind. Can Yeonwoo (call sign: Cain) navigate that world and gain enough power and experience to reach the top of the tower, defeating his brother’s enemies and all those who stand in his way?
