"Everyone has a purpose. You just haven’t found yours yet.”

Shako Ikitayashi is a high school boy burdened by family conflict and poor social skills. Ever since he was young, he’s felt the world was against him. But nothing could have prepared him for what happened on that day, when he was possessed and forced to end his own life.
When he wakes up, Shako finds himself in a strange new world—and is dragged into a conflict that has lasted for thousands of years. In this world, he finds allies who open his eyes to life’s deeper meaning, and who may help him uncover the answer to his greatest question: "What is my true purpose?"
