As the young priest/manager of the temple surrounded by girls-only schools, Kagetsuna tries to turn the temple into a couples dating service temple to help raise a profit. Unfortunately for him, the god that gets assigned to his temple turns out to be a war god, Tonari. In this peaceful world, Tonari's war powers only bring unwanted chaos and not a lot of help for Kagetsuna's promotional ideas.
