Judas, cursed for his sins, is the spirit of Death--he is without form, and has enslaved young Eve to carry out the most heinous of acts. Together in spirit and body, they must slay 666 people so that Judas can regain his humanity.
Using Eve as his vessel of destruction, Judas' dark, blood-soaked journey will leave a trail of sin, death, and--hopefully for Judas--redemption.
