Having gotten their dungeon-diving legs, Kei and Miyoshi receive some special proposals. Both the Japanese Dungeon Association and an international mogul request for the two former company researchers to head into the dungeon depths to retrieve rare skill orbs! But can Kei and Miyoshi’s smarts help obtain a D-Card for someone unable to enter the dungeon on their own? They’d better hope so! A highly coveted table at a fancy restaurant is on the line! Plus, D-Powers finally come face-to-face with the United States’ top dungeon exploration team!
