Dark Knight EX Vs. Psychic Wizard

The demon world has been around for tens of thousands of years, and there are too many demon kings sealed away, so a group of little demon kings are expelled from the demon world. They are called demon masters, who specialize in controlling people's desires and bringing destruction to the world. Most of the magic masters' unique skills are possessed by people, and Dark Knight EX belongs to a mortal made of steel alloy. The personality is neither good nor evil, but every time you defeat a demon master, you can absorb its energy, thereby healing wounds or evolving and upgrading. In order to have power that rivals the universe, EX came to the past world, the real world, the future world, as well as the sky and the demon world to crazily sweep the demon master.
