Koto doesn't know she broke the world, and watching her figure it out while pretending to be competent at priestess work is comedy gold. The show stacks weird monsters, shrine maiden chaos, and actual stakes on top of each other without ever losing the thread that this is fundamentally about a girl trying to fix a problem she caused. By episode eight you realize it earned every joke it made.
Without realizing it, Koto seals away the Sun Goddess Amaterasu and ends up in a different world with no way back. There she meets priestesses who fight the evil of this strange place, and she learns that Black Towers spread across the land keep Amaterasu sealed. Evil monsters guard each tower, and Koto has to find a way to help defeat them and put the world back the way it was. The short-format series mixes action, adventure and fantasy with comedy and ecchi humor.
