Akira joins the bounty hunt with Shikarabe and the other Druncam veterans. But right before they set off, Shikarabe asks Akira to let a young rookie named Togami accompany him. The conceited Togami can’t believe he has to team up with someone who looks as wimpy as Akira, but as the two boys fend off the wasteland’s monsters, Togami quickly realizes his mistake. And just in time, for when the mighty tankrantula—a behemoth worth 800 million aurum—appears, veterans and rookies alike must fight together with their lives on the line!
