Berserk

Guts, known as the Black Swordsman, is a lone mercenary warrior who travels a dark, medieval-esque world. Armed with his massive sword Dragon Slayer and bearing the Brand of Sacrifice upon his neck, Guts is pursued endlessly by demons while hunting the man who betrayed him—Griffith. A former comrade who sacrificed the Band of the Falcon to become a godlike entity, Griffith now rules a kingdom with divine power. Guts' journey is one of revenge, survival, and rediscovering his humanity amidst a world of unrelenting cruelty and supernatural horror.
