A new discovery in a previously mapped out dungeon might be the first step toward Kazuma repaying his massive debt. Unfortunately for him, Aqua is determined to help.

Kazuma is surprised to discover that Vanir had an extra life and has since quit his position as a commander to work at Wiz's shop, striking up a business partnership to sell products from Kazuma's world.

Kazuma and the others manage to lure the kite hawks into a cave and deal with them all at once, only to cause more trouble for the other travelers later when Aqua attracts some zombies.

After defeating Sylvia at the Crimson Demon Village, Kazuma and his party look forward to receiving a reward that could mean freedom from the grind of having to fulfill quests. Kazuma himself, however, seems to be having nightmares and bouts of paranoia.

Kazuma and his friends return to Axel and receive 300 million eris as a reward for subjugating Sylvia, an executive of the Devil King's army. Kazuma and Aqua go to high-end restaurants, and Aqua enjoys her long-awaited life as a celebrity.
