Darkness, Aqua, and Megumin are back to continue their quest against the Devil King. Kazuma is back too, but the only adventures he has waiting for him exist within the criminal justice system

Kazuma and Aqua meet Yunyun, a Crimson Demon girl who claims to be Megumin's rival. The feuding magic users then square off in a competition that could have ruinous repercussions for both of them

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

Darkness is back, but not to stay, if Kazuma and her father have anything to say about it

As a result of a magic circle that Aqua had drawn in Keele's dungeon, strange explosive doll monsters have started to appear, putting the town at risk

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

Vanir gives Kazuma the choice of either selling the intellectual rights for his real world products for a one-off payment of 300 million eris, or maintaining a profit-sharing contract of 1 million eris a month

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

The party makes their way to Arcanretia, a city known for it's recuperative hot springs! But what they don't know about the city might spell doom for their vacation

Evading the angry mob, the gang discover that the source of the town's water is being poisoned by the man from earlier, who is revealed to be one of the Devil King's army leaders, Hans the Deadly Poison Slime
