Kouji Tatsuishi

Born as the second son of the Tatsuishi family—a prestigious household known for its supernatural abilities—Kouji served as the sole emotional anchor in Miyo's childhood years. Despite harboring genuine and deep feelings for her, his weak-willed nature left him unable to defy his father's wishes, ultimately forcing him into an engagement with Miyo's younger sister, Kaya. The traumatic incident of Miyo's kidnapping confronted him with the harsh reality of his own helplessness, spurring him to journey to the old capital for rigorous training and to enlist in the military, determined to grow strong enough to protect those who truly matter to him.
