One day, black vortexes appeared above cities everywhere. They were gateways from Hell.
Humanity was on the verge of collapse. Growing stronger was the only choice.
The Realm of Hell was burdened by the obsessions of countless vengeful souls and evil spirits.
In a treacherous, eerie inn, a snake lurks in the shadows of the underworld...
In a mysterious, silent ancient city, there is a city lord whose nature is impossible to fathom...
A lone train with no way home heads for a forbidden land of death...
The human world and Hell collide. Evil spirits run rampant, and vengeful ghosts claim lives.
