A semi-serious school action story revolving around the main protagonist, Tomoharu Natsume. He is haunted by his childhood friend, Misao Minakami, who became a ghost ever since he barely survived an airplane accident three years earlier. Tomoharu Natsume takes the opportunity to live on his own when he enters high school in his new place of residence, Meiou-tei, and starts enjoying a carefree high school life. His life changed when a beautiful girl named Kurosaki Shuri appears with a trunk which she claimed Tomoharu's brother, Naotaka Natsume, asked her to deliver to him. The presence of the trunk causes the appearance of Takatsuki Kanade, a girl dressed like a shrine maiden who is after the trunk. Tomoharu is in possession of the trunk, which reveals secrets about the world they live in.
