Born from the corpse of his mother, a young mercenary known only as Guts, embraces the battlefield as his only means of survival. Day in and day out, putting his life on the line just to make enough to get by, he moves from one bloodshed to the next.

After a run-in with the Band of the Hawk, a formidable troop of mercenaries, Guts is recruited by their charismatic leader Griffith, nicknamed the "White Hawk." As he quickly climbed the ranks in order to become the head of the offensive faction, Guts proves to be a mighty addition to Griffith's force, taking Midland by storm. However, while the band's quest for recognition continues, Guts slowly realizes that the world is not as black-and-white as he once assumed.
