Hell has broken loose in the kingdom of Midland. On the death of Midland's king comes invasion, demonic forces seem to be on the rise, underground pagan cults are running wild, and the church is busily rounding up and teaching heretics the errors of their ways. While, Guts is busy testing out his newly repaired sword on the invaders, his former captain and lover, Casca, her mind wrecked by her unholy tryst with the demon lord, has fallen in with a rough crowd who don't exactly wish her well.
