Berserk (1997–1998)

Kenpuu Denki Berserk adapts the early arcs of Kentaro Miura’s manga, following mercenary Guts as he joins the Band of the Hawk under the charismatic leader Griffith during a period of constant warfare. The series blends dark fantasy with psychological drama, focusing on ambition, loyalty, and the brutal realities of medieval conflict. Its grounded tone, character-driven storytelling, and gradual shift toward the supernatural form the foundation for the larger Berserk narrative.
