The protagonist, an apprentice onmyoji (Japanese exorcist), begins a live-in apprenticeship in Kagurahama Town to become a full-fledged onmyoji. With a completely new home and high school, they dive into this unfamiliar world filled with both excitement and anxiety.

One day, the protagonist accidentally involves a female classmate, Hana Homusubi, in a youkai extermination and ends up causing her serious injury.

In a desperate attempt to save her, the protagonist transfers some onmyoji power to Hana, which heals her — but unexpectedly, the power transforms her into a Magical Shrine Maiden.
