Isekai Onmyouji to Juuni Tenshou no Shikigami

Also known as: 異世界陰陽師と十二天将の式神, The Exorcist and the Shikigami of the Twelve Heavenly Generals in Another World, Reincarnated as a Son of an Aristocrat

by Hakuto Aono, Kei Kokonotsu

The strongest onmyoji in history, the master of all spiritual techniques and served by the Twelve Heavenly Guardians as his shikigami, was tragically betrayed and killed. However, on the verge of death, he managed to transmigrate his soul to reincarnate in another world. He became Wayne, the third son of a high-ranking aristocrat. In this world, magic was commonplace and status is determined by one's magical ability. Of course, no one knows anything about spiritual powers or shikigami here. Wayne had zero mana and had no talent for magic. However, he retained his onmyoji powers and the memories of the spiritual techniques from his previous life. With his mastery of spiritual powers and his shikigami servants, the incompetent Wayne will accomplish the impossible. The adventure of the most powerful onmyoji, beyond the comprehension of the people in a magical kingdom, begins now. (Source: Hyke Comic, translated)
