Guts, the feared Black Swordsman, is on the rampage. Mozgus, the malefic master Inquisitor of the Holy See, in his murderous campaign against heretics, has captured Guts' former lover Casca and has her at the ready to be burned at the stake in the Tower of Conviction, little knowing that Casca's demonic Mark of Sacrifice is drawing hideous dark powers to the Tower. It'll take everything Guts has and more to defeat Mozgus - who is much, much more than a man - and even if he can, will he be able to save Casca from the hordes of Hell amidst the inquisitor's disintegrating citadel?
