It had been a rather normal day, well as normal as things could get in this God-forsaken place. At least it WAS until a giant tower decided to spring itself out of the ground in the center of the city. And just for added fun this wasn't just some tower, oh no, it was the Temen-Ni-Gru, the mother of all portals to the demon world and with it came hoards of demons.
The tower itself though, has not yet been activated but if and when someone does get the giant thing powered up and running, the world as we know it will cease to exist and all that the Legendary Dark Knight Sparda had fought for will mean nothing.
So will you help the newbie demon slayer Dante as he fights just as Sparda did to help the human world or do you prefer to play on Vergil's side and help him try to make the human world his own demonic realm. The choice is yours to make.
