Akira is riding high after his successful rescue operation. With new gear and new friends, he’s ready for the next phase of his relic-hunting career. But Akira isn’t the only young hunter in the wastelands, and success might just paint a target on his back. Katsuya, a rookie with the hunter syndicate Druncam, is desperate for recognition, but the veterans around him are more interested in Akira’s feats. Unaware of how much support Akira receives from the ghostly Alpha, Katsuya struggles to outdo his fellow up-and-comer, pushing himself and his friends into ever greater danger in the process. But just when it seems he’s pushed his luck too far, Katsuya has a mysterious encounter of his own. When a major job throws these two young hunters together, Akira must come to grips with Katsuya’s one-sided rivalry while facing down a nest of new and deadly monsters.

Akira has only spent two days exterminating the heavily armored scorpions hiding out in the underground tunnels, and he’s already had more close calls than he bargained for. And try as he might, his bad luck’s about to get worse. A chance encounter soon proves that the biggest threat in the tunnels aren’t monstrous bugs but other humans. Now a gang of cyborg relic thieves have him in their crosshairs, and his fellow hunters may not take his side. With his lines of communication cut off, and forced to fight new enemies and old allies, Akira is outclassed, outgunned, and out of options. How will the young relic hunter stop a threat that can pursue him from beyond the grave? As Akira fights for survival, the scheming ghosts of the Old World look on...

Akira has come a long way from his life on the streets. He’s a proper hunter now, with a roof over his head, food on his plate, and cash in his pocket. And under the guidance of the mysterious Alpha, he continues to acquire superior weapons, skills, and gear. But success has its downsides, and unfamiliar threats are hurtling toward him—both in the desert wastelands and in the city streets. Akira’s deal with aspiring gang leader Sheryl puts him in conflict with the rival bosses eyeing her territory, and it’s going to take more than firepower to navigate the web of schemes and alliances ensnaring the slums. Meanwhile, a massive swarm of monsters bursts out of the ruins, heading straight for Kugamayama City. Rushing to answer the call for help offers Akira a fresh chance for advancement, but the real danger may prove to be his fellow hunters...

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?

With the gang war behind him and touting a brand-new set of gear (again), Akira is ready to dive back into the ruins for relics once more! In the depths of Kuzusuhara, the enigmatic Alpha guides him to an Old World city. There he encounters Tsubaki—the AI managing the area—who seems to hold a grudge against Alpha! Meanwhile, Sheryl’s relic shop finally opens for business. All is going well for Akira, but the city seems to have other plans for him. Many lives hang in the balance as conspiracies unfold and the Old and New Worlds clash!

Akira has learned the hard way that his fellow relic hunters can be just as deadly as anything else in the wasteland. He’s more determined than ever to go it alone, but life has other ideas. Suddenly, fortune seekers are crowding his favorite hunting grounds, and when a mysterious phenomenon blankets the ruins, he finds it harder to steer clear of conflict than he’d like. Back in the city, his luck isn’t much better: one of the many gangs that rule the slums is out for his money—and his blood. Compared to the ravenous beasts and killer machines that roam the wastes, these petty outlaws don’t seem much of a threat—but they won’t stop coming after him until he racks up a body count that shows gunning for him doesn’t pay. And to cap it all off, he crosses paths with a girl who might just end his self-isolation for good. Akira has an arsenal of new gear and the ever-mysterious Alpha to guide him, but will that be enough to navigate the rocky road ahead?

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.
