D succeeded in making it through the final exam and achieved his final goal of being promoted to a full-time Ranger…even better, he defeated the Blue Keeper and stole his divine artifact. If only he didn't have to share credit with the boss monster, Peltrola. Now, as D enters the Green Squadron with his fellow recruit, Usukubo, he prepares to take down a new target: The Green Keeper! What's more, there seems to be another boss monster lurking around the neighborhood. It's time for a brand new undercover op. If D is discovered, it's over—and what's this about a series of mysterious disappearances around town?
