Berserk manga volume 20 features story and art by Kenturo Miura.

The Black Swordsman Guts' former captain and lover, Casca, has been taken by the Holy Iron Chain Knights to the "Tower of Conviction." There waits the fanatic torturer of the Holy See, Mozgus, who plans to treat the rumored witch to the proper agonies of the damned.

Guts is on his way to rescue Casca and dish out some chastisement of his own on any who get in his way, but forces in the demonic realms are in motion and are being drawn to the torture tower. It may all be a prelude to a second Eclipse and an unprecedented release of malign spirits into the world!
