I, Ashiya Michimi, Am Walking Sideways in the Magic World

The Great Onmyoji Ashiya Michitsu was defeated by Abe Seimei, but his soul accidentally traveled to a different world of magic, and he became a "waste" son with no talent in the eyes of his family. While everyone could bully him and humiliate him, he secretly reunited the power of the spell and merged it with magic. With a snap of his finger, gray flames surged into the sky, showing the world the fangs from Heian Jing.
