The bejeweled Felisi City has long passed with the passage of time during the war between gods and demons. Now the people of the Falma Continent have become numb with the storm of darkness. Recently, there has been widely circulated information that the three demon gods will once again bring darkness to the entire Falma Continent. In order to completely eliminate evil, Marisius, a human hero, selflessly used his body to seal Diablo's evil soul. But he was wrong, precisely because the evil soul of Diablo, the king of destruction, entered and used his body of light to realize the advent of darkness step by step.
