Berserk, Vol. 1

By

Rated 4.49 out of 5 stars, based on 69,022 reviews.

Berserk, Vol. 1 by Kentaro Miura introduces Guts, the Black Swordsman, a brutal mercenary marked by a cursed Brand that attracts demons and other supernatural horrors. Armed with an enormous sword and a mechanical arm, he carves his way through a medieval dark fantasy world filled with violence, corruption, and occult forces. Joined, somewhat unwillingly, by the talkative elf Puck, Guts pursues a path driven by rage and survival rather than heroism. This first volume of the seinen manga establishes Berserk’s blend of graphic action, horror elements, and bleak atmosphere that defines the long-running series.

The volume unfolds as a series of atmospheric episodes that blend fantasy and horror, focusing less on action and more on unsettling encounters, moral ambiguity, and the fragile boundary between human life and other forms of existence.
