Rebuild World: Volume 3 Part 2 [EPUB ebook] 

Akira has made it out of Yonozuka Station alive, but he’ll have to put his next relic hunt on hold—the ruin’s drastically altered ecosystem is spawning mutant behemoths, rendering the wasteland unsafe. The Hunter Office steps in and offers a large bounty for exterminating them, leading to an enticing proposition for Akira from an unlikely source. Meanwhile, the internal conflict within Druncam escalates. Akira must now face deadlier foes than ever before, and this time Alpha’s support might not be enough!
