Noctis Ashima is a former high paying marketer, about 23 years old, with a tragic past and that past links him to a trending but deadly game named RPG Fantasion. His brother and father have long since entered the game dimension. After his brother's death, he's called on by his father to replace his brother in the game, avenge his brother's death, and beat the game. He joins the fray. Along the way, he has a sexual and romantic relationship with various female players of the game. He eventually collects powerful elite allies. They have to go through a lot of trials and fierce battles before they finally reach the last floor of the game. An epic and fierce grand battle unfolds between Noctis, his allies, and the Game Creator's most strongest beast. To make things even more challenging, the Game Administrators and Game Guardians are split into two factions. One faction wants to give players from various dimensions some power and allow them to log out safely, while the other faction wants to keep things the way they are, monopolize power, and allow only the elites to log out after they beat the game.
