Akira ( アキラ ) is the protagonist of Rebuild World series. He was a boy who lives in a slum in the eastern city of Kugamayama. He is an orphan boy, and little is known about his childhood apart from the fact that he lived on the streets, and had to fend for himself for most of his childhood.

Hunters brave the ruins of a long-dead civilization at the behest of the corporate city-states who thrive on its detritus. Amidst the decay lie powerful artifacts of ancient technology, eclipsing anything the corporations can develop. For a few successful hunters, the search for these relics is a road to untold riches. For most, it’s a shortcut to slaughter at the hands of mutant bioweapons and robotic sentinels. And for those trapped at the bottom of society, it’s the only way out. Akira is uneducated, underfed, and unprotected—just another homeless kid in the sprawling slums between the walls of Kugamayama City and the deadly wastelands which surround it. Relic hunting offers his only hope of clawing his way to a better life outside the slums. But his first, desperate foray into the ruins threatens to end his brief life—until he meets a mysterious, incorporeal woman named Alpha.

The pinnacle of human civilization has come and gone, leaving only ruins in its wake. Society and science now struggle to rebuild, rediscovering scraps of knowledge from powerful ancient artifacts that defy comprehension. These relics of the “Old World” can make the fortunes of those who find them—if ancient security systems and rogue bioweapons don’t kill the relic hunters first. Akira, a young street orphan, sets out to become one such hunter to escape his brutal life in the slums. Untrained, malnourished, and poorly armed, Akira would be lucky to make it back from the ruins alive—until an encounter with Alpha, a mysterious, ghostly woman, changes his fate forever. Alpha needs a hunter, and she’s willing to train Akira to get one. Will her support be enough to help a penniless kid from the slums climb to the top of a crushing and merciless world?
