Akira Nikaidō, a typical slacker living a normal life in high school, encounters a mysterious man named Shirogane who tells him that they have a destiny together. When Akira hears this, he is shocked and doesn't believe a word of it.
One night, Akira accompanies his friend Aya Suzuno to their school so that she can find a forgotten item. He agrees, and while there, they are attacked by a Kokuchi. Shirogane appears and tells Akira of the distortion of balance between the Human World and the Shadow World, saying that for him to restore balance, he must become a Shin: a being of the Shadow World. Shirogane, wanting to be with him, lied that if he became his shadow he will be seen by other people again. However, Akira is later informed by Shuichi Wagatsuma that he doesn't need Shirogane to become his shadow because he has an object, one that can become his shadow once he steps on it.
But then Akira's friends, Aya and Kengo Asamura, see Akira and Shirogane while they're as Shin. After initial hesitation, Akira decides to let the two join him and Shirogane as they restore balance to the Human World and Shadow World.
