Guts, an immensely strong sword-for-hire, has little direction in his life, simply fighting one battle after the next. However, this all changes suddenly when he meets and is bested by Griffith, a beautiful and charismatic young man who leads the Band of the Hawk mercenary army. After Guts joins the Band and the relationship between the two men begins to blossom, Casca, the tough, lone swordswoman in the Band of the Hawk, struggles to accept Guts and the influence he has on the world around her. While the two men begin to fight together, Griffith continues to rise to power, all seemingly in order to reach his mysterious, prophesied goals. What lengths will Guts and Griffith go to in order to reach these goals, and where will fate take the two men?

The Band of the Hawk and their enigmatic leader Griffith continue winning battle after battle as their prestige throughout the kingdom of Midland grows. But their latest task is one that has seen failure from everyone who has attempted it: the subjugation of the impenetrable fortress of Doldrey.

One year has passed since Guts left the Band of the Hawk and Griffith was imprisoned by the Kingdom of Midland for treason. In the dead of night, at a camping site where they hide, the Band of the Hawk is attacked by Bakiraka assassins led by Silat. When all seems lost, Guts returns from his journey. "You destroyed everything." Crying that Griffith is nothing without Guts, Casca and Guts are joined together body and soul. Griffith is imprisoned in the oldest building in Wyndham Catle, the Tower of Rebirth.
