The second season of Dungeon ni Deai wo Motomeru no wa Machigatteiru Darou ka.

There's rarely a dull moment when you're the champion of a tiny Familia, and things only get rougher for Bell when the God Apollo declares war on Hestia and her followers. With Apollo's Familia able to field a hundred times as many men, Hestia will have to work a lot of favors to keep her Familia from being completely destroyed. Even if Bell and Hestia manage to pull off the impossible, a major debt that Hestia owes is about to come due and Lili's sordid past comes back to haunt her!
