(A story synopsis for the game. No spoilers are in here and is just a basic overview of the beginning of the game)
Set in the near future, the biblical apocalypse is upon the world. The armies of Hell and Heaven prepare to clash over Earth, and Satan knows his victory is assured. The only thing he requires is the key to the apocalypse, the Anti-Christ. While he was being born on earth, a religious cult known as Judah stole the baby before his demonic power could be developed. The mark of the beast, 666, that was on the back of his neck was sealed, making it so the boy would not have access to his power and after a while would neutralize his demonic power, making him human. Satan, fuming with rage puts all his forces to one task: bring him back alive. 17 Years later, Iijin is living with his father, Joseph, happily. One night a group of demons ravage the town (normal humans can't see demons, any damage or deaths caused by a demon just appears to be an accident to humans: i.e getting hit by a car) Joseph notices their presence and prepares to face them. However Satan himself challenges him. Joseph, after a long battle finally realizes that he cant win because Satan is immortal. Iijin is awakened by the noise of the battle and arrives to see Satan about to kill his father. Satan grins and says "My my, you've grown quite a bit, my son." and then kills Joseph. He then unlocks one of Iijin's 6s, unable to unlock them all and disgusted by his strength after 17 years severely beats Iijin tells him to gain power, and come to him so that the plan may continue. Iijin wakes up the next day to find his town destroyed and everybody dead. An angel has arrived on the scene to investigate the matter, preparing to kill Iijin because of the demonic energy he now emits. The angel seems puzzled because Iijin cant fight back. After questioning him he tells Iijin "You are the Anti Christ, heir to Hell's throne." Iijin says "the only thing that I want is him dead, but he's immortal, its impossible." The angel laughs, "The throne is passed through your lineage only when the previous Satan s killed by his heir. So not only do you have a need to kill him, you're also the only one who can." The angel then tells him his name is Forun and that he will help him to kill Satan, but if he thinks Iijin is just in it for the throne, he'd have to kill him. After this the two decide to get to Hell by using the closest gate which is on the other side of the continent. Satan, knowing that the demonic thirst for vengeance will bring Iijin to him and decides to give the order that all demons are to kill Iijin, hoping that if he survives this it will make him stronger and if not, he was a waste not worthy to live. Elsewhere Judah learns that the Anti-Christ is moving. Needing his power for their own goals, The 12 Tribes, The 12 lead members of Judah, give the order to their followers: Capture the Anti-Christ alive. All the pieces are now set up for a battle that can shape the world, or cause it's end.
