Your favorite cozy camping anime returns with a movie as the former members of the Outdoors Club get together again, this time to build a campsite! Reunite with Nadeshiko, Rin, Chiaki, Aoi, and Ena as they gather around the campfire once more with good food and good company.

In the city of Orario, beneath an impossibly tall tower, lies the dungeon. Only adventurers who form partnerships with the gods themselves have any hope of defeating the monsters that lie within. But the dungeon is not the only place where monsters exist. Far from Orario, in the ruins of an ancient city, a new threat arises. To counter this threat, the goddess Artemis has come to Orario in search of a champion—but it’s not Ais Wallenstein (the legendary Sword Princess) nor Ottar (the strongest warrior to ever enter the dungeon) that she chooses. Rather it is Bell Cranel, a newbie adventurer partnered with a low-tier goddess.
