Is It Wrong to Try to Pick Up Girls in a Dungeon?: Arrow of Orion (Blu-ray release 2019-7-31) is the movie following the first season of the anime adaptation of a light novel series. This movie assumes knowledge of the first season about who everyone is and what their relationships are. Although the story is self contained, I would not advise people to watch this movie without watching the anime series first.
The protagonist won a travel trip by pulling out a sword that no one else could, but of course this is merely a scheme to get him to go on a quest to defeat a monster. The movie is rather straight forward especially considering it is hinted in the middle about what should happen at the end. For fans the harem aspect is maintained as again we see the jealousy among the different female characters, especially involving the new goddess. I do not think the relatively short dialogue involving her in this short movie is enough to establish the emotional core. For the level of threat that the story implies, the city is too well defended to have a sense of urgency, but otherwise the movie is safe and is neither surprisingly good nor bad.
