Plot.
The story is a semi-serious school action story revolving around Tomoharu Natsume. He is haunted by the ghost of his childhood friend, Misao Minakami, who died in an airplane accident three years earlier, which Tomoharu barely survived. On entering high school, Tomoharu takes the opportunity to live on his own and moves into Meiou-tei, a dormitory, where he starts enjoying a carefree high school life (also, his mother has recently remarried and doesn't want him interfering in her newlywed life). His life changes when a beautiful girl named Shuri Kurosaki appears with a mysterious trunk which she claims Tomoharu's brother, Naotaka Natsume, asked her to deliver to him. Things become complicated when Kanade Takatsuki, a girl dressed like a shrine maiden, appears seeking the trunk in Tomoharu's possession. It is revealed that the trunk hides secrets about the world they live in.
