Perverted Demon

With the Greatest Demonic technique in his hands, one can turn mountains upside down and can make rivers of blood flow backwards.

One can make constellations bow to his might and one can have gods serve to him as his servants.

Or one can peep into bathing girls.

This is the story of the greatest Demon ever existed in the history of Twelve Great Heavens.
