Chapter Summary: What would you do if you were just a normal high school kid and then suddenly everything changed? Akira Nikaido was in that situation. He was approached by a man named Shirogane to meet him one night at the school. Akira went and was then attacked by shadow monsters. Shirogane explained to Akira that the balance between the human world and shadow world is now messed up and now Akira needs to take on the role of a shin (a shadow world creature) so he can restore the balance.
