Plot
Rebuild World takes place in a post-apocalyptic world, decades after an unknown cataclysm. While humanity perseveres, a majority of the population lives in squalor, only the wealthy and privileged able to eat any food which is not experimental rations. The primary way to survive in this world is by becoming a hunter—exploring the ruins of the "Old World" to find lost technology, as well as combatting the numerous organic and mechanical monsters that were born from the collapse in society.

Akira is a street orphan who wants nothing more to become a hunter, so that he can find old technology and sell it to live a better life. However, his first foray into the city ruins almost ends in disaster. Akira’s life is saved by Alpha, a mysterious artificial intelligence that communicates to him alone using augmented reality. Alpha explains that she is looking to explore a particularly dangerous part of the Old World, but is physically unable to do so. Alpha offers Akira a proposition: she will act as his guide, training him in combat and teaching him how to operate as a hunter, in the hopes that he can explore the ruins for her. Akira agrees, and the two soon become entangled in the dangerous world of technology hunting.
