Why is someone whose entire being is filled with an aura that doesn't belong to this world still able to exist as if nothing were wrong? What should you feel when you see your own death notice with your own eyes? An ordinary boy dies in an accident, then unexpectedly comes back to life. As a remnant soul lingers and his own soul changes, he becomes almost less than human, stepping into a world where ordinary people dare not tread. As his powers grow, he learns another side of this world, along with its truths. This world is far more complicated than we imagine, full of countless unbelievable things.
