Star Demon Swordsman

People practice magic, but he practices swordsmanship. Can magic be defeated with a sword? Of course, does the cheating life need an explanation? No explanation needed. He is the only horned devil in the world. Unlike humans, he has horns on his head. In this world there is frightening forbidden magic, a house of magical swordsmanship that has been passed down for thousands of years, and technologically advanced mechanical transformation people. This is a world dominated by magic, and everything in the world is made up of magic.
