After D-Powers shocked the world by auctioning off skill orbs—the most precious and ephemeral of items—the JDA tasked Keigo and Miyoshi with finding the Otherworldly Language Comprehension orb. This rare item could spark wars between nations in the wrong hands, but it could also make D-Powers obscenely wealthy. To find it, Keigo and Miyoshi must delve deeper into Yoyogi Dungeon than ever before, facing new dangers, testing out their many skills, and learning what it truly means to be an explorer along the way!
Back on the surface, government agencies across the world are also starting to move—some hoping to aid D-Powers, while others seek to thwart them. This time, Keigo will have to face enemies far more dangerous than slimes, goblins, or even undead monsters…all in a day’s work for the world’s laziest top-ranked explorer!
