Not a harem, not invincible, not systematic, not brainless, not cheating. The protagonist will not defeat ghosts and gods with one punch, nor will he become invincible overnight. All he can do is use an ultraviolet lamp, a sound wave detector, and a determined heart to prove that there are no ghosts in the world, only people who pretend to be gods. Those who mind slow reading, mind-burning, and lack of interesting rhythm should be advised to enter with caution.
