It opens like a municipal promo video, because it is one, and that is exactly the joke that lands. Mitora Ootsuchi works the tourism desk at Ootsuchi Town Hall, and the first stretch is her and her coworkers rehearsing a sightseeing pitch, hitting the Gensui River and Kozuchi Shrine like they're filming B-roll for a pamphlet. Then a demon beast shows up and the pamphlet becomes a battlefield, and the show cashes in every tag it's carrying: mecha, supernatural, the whole overblown Chou Kagura Dai Hammer of it. Eleven minutes of local-government earnestness weaponized, with a heroine whose stake in saving the town is that promoting it is literally her job. Fans who found it call it slept on, and they're right, because nobody expects a regional tourism ONA to swing this hard. Watch it, then look up whether the shrine is real.

Mitora Ootsuchi works in the tourism department at Ootsuchi Town Hall. She is taking part in a rehearsal with fellow staff members to promote the town, visiting local spots such as the Gensui River and Kozuchi Shrine. Partway through the tour, a demon beast attacks without warning, and Mitora and her friends are left facing the task of saving their town. The single ONA episode mixes action, mecha, science fiction and supernatural elements.
