One of Miura Kentaro's debut works. It's a short story about survival in a post-apocalyptic era.

100 million years after the Great Destruction, life hangs on in the wastelands with humans, demi-humans, and massive creatures fighting for survival. With the Empire of Olympus using colossal beasts to crush their adversaries, only gladiator Delos, mystic Prome, and the titan Gohra they become can hope to stem genocide and heal the shattered Earth.

Rick has lived a normal life as a mechanic's apprentice in a world underground. That, however, is about to change as he bumps into a strange intruder who is not quite like anyone Rick has ever seen before. Venus, the intruder, claims to be from another world just like Rick's, though slightly different. With the police after Venus, can they figure out what is going on?

Guts, known as the Black Swordsman, seeks sanctuary from the demonic forces that pursue him and his woman, and also vengeance against the man who branded him as an unholy sacrifice. Aided only by his titanic strength, skill, and sword, Guts must struggle against his bleak destiny, all the while fighting with a rage that might strip him of his humanity. Berserk is a dark and brooding story of outrageous swordplay and ominous fate, in the theme of Shakespeare's Macbeth.
