A mysterious man arrives at Dante's yet-unnamed shop with an invitation from Dante's brother Vergil. A huge tower erupts from the ground nearby, eclipsing the city surrounding it. Sensing that Vergil is on top of the structure, Dante interprets this as a challenge. He soon crosses paths with a mysterious woman on a motorcycle who also seems to be on a mission of her own. What is Vergil planning, what does the lady want and what lies at the top of that dark, looming tower?
