Versatile Mage's Sharingan

Because I like this book so much, I specially opened a new book. According to legend, on the other side of the earth, there is a magical civilization that is completely opposite to the earth's technological civilization. It has no guns but magic. What is rampant on the earth are demons and humans struggling in the gaps of the world. A boy who had just traveled to Naruto died on the night of the Uchiha genocide and came to this world with his Sharingan. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
