Guts
Guts is the protagonist of the story. A tall, muscular male with a huge sword called the Dragon Slayer, a prosthetic left forearm that has a magnetic grip, and also conceals a cannon. Guts is a tragic hero; he is born as one who may be able to struggle against Causality, but seemingly unable to affect it on a large scale.
Caska
Caska was the only female soldier in the original Band of the Hawk and is behind only Gatts and Griffith in swordsmanship. Her ambivalent relationship to both of them makes her moody and capricious. Caska joins the Band of the Hawk after Griffith saves her from a sexual assault by a nobleman. After Griffith is imprisoned, she becomes the leader of the Band of the Hawk and, along with Gatts, leads the mission to rescue Griffith.
Griffith
Griffith is the founder and leader of the mercenary army Band of the Hawk. Extraordinarily charismatic and handsome, his tactical skill gives him and his army the reputation of invincibility, making him the favoured choice of the Midland King, who was locked in a century long war with the Empire of Tudor. Griffith is willing to sacrifice everything for his dream of his own kingdom, believing that he is destined for things greater than the average man.
