Dungeon ni Deai wo Motomeru no wa Machigatteiru Darou ka Movie: Orion no Ya S01

In the city of Orario, beneath the towering and impossible-to-reach tower, lies a dungeon. Only adventurers who form contracts with gods have hope of destroying the monsters within it. However, the dungeon is not the only place where monsters exist. Far from Orario, in the ruins of an ancient city, a new danger emerges. To counter this danger, Saint Artemis has come to Orario in search of a hero - but the hero is not Ais Wallenstein, the legendary sword princess, or Otar, the strongest warrior to have ever entered the dungeon. Instead, she chooses Bell Cranel, a novice adventurer who has formed a contract with a low-ranking goddess.
