Or why you don't bring your goddess to the goddamn dungeon.
This movie would take place after season 2, but maybe before the ending of Sword Oratoria. It doesn't matter, it's not canon. It's basically a short arc with slightly higher production values. It's a fun watch if you loved season 1 because it's more of the same. It was nice to see some of that power of the gods on display though. Still, this could have been avoided if a certain goddess wasn't an idiot. Honestly, the story in this is pretty much a fanfic: new, awesome character that already knows some of the cast and is somehow connected to the MC. Acts like a love interest. Is forgotten the moment the movie ends, never to be talked about again.
These are official subs from the US BD, but the video is from the JP BD. Stereo and surround Japanese audio.
PS: No, I'm not calling it "Arrow of the Orion".
