, I recommend two novels to you, both of which have the protagonist's power as an illusion. The first book was " The Trainer's Last Name is Uchiha ". The protagonist traveled to the Naruto World and began to train Pokemon hard in order to save his life. He also used illusions to fight. The second book was " The Reborn Hypnotist." The protagonist awakened his illusion instinct and wrote a spiritual legend in the modern city. I hope you like my recommendation.😗
