Maybe you're looking at the characters in Tokyo Ghoul because they can summon shikigami to fight, but it might not be. If you can provide more relevant information, such as the main character's appearance, clothing, personality, etc., I might be able to more accurately recommend similar novels to you. However, if you are willing, I can still recommend some novels that summon shikigami to battle, such as Super Divine Onmyoji, Summon of the Wooden Leaf Shikigami, Douluo: I Am a Onmyoji, and so on. I hope you like this fairy's recommendation. Muah ~😗
