Kazuma Satou and his dysfunctional party, made up of the goddess Aqua, the explosion-obsessed Megumin, and the masochistic crusader Darkness, tackle two standalone bonus episodes set after the third TV season. In one, an approaching typhoon puts the town of Axel in the path of chaos; in the other, a suspiciously familiar adventurer named Ozuma Zatou shows up looking for Kazuma by name. This two-episode OVA supplements the third season with standalone comedy.
