Seimei Aoyagi (青柳 清明)

Ritsuka's older brother. He was seventeen when he was found murdered, although he died under mysterious circumstances and could only be identified by his dental records.


When Ritsuka lost his memory, Seimei stepped in and became an extremely important figure in his life. He protected Ritsuka from their abusive mother, Misaki, and was a great source of comfort and trust. As a result, Ritsuka was hit hardest of all by the news of his brother's death. He is very bitter and vengeful towards those who may have been involved in the killing of his brother.


In flashbacks in later manga chapters, it has become increasingly clear that Seimei suffers from mysophobia, a fear of contamination of dirt or germs, although it is largely reader speculation based off his obsessive behaviour about cleanliness and such innocent items such as homemade food being "dirty."

Currently, he and Nisei, the true Beloved fighter, have traveled to Goura and has infiltrated the Academy of Seven Voices. His reasons for this infiltration has not yet been revealed. He betrayed Nisei by refusing to assist him in a two vs. one spell battle with Ritsuka and Soubi. This kind of action is very much consistent with the many negative beliefs that most of the characters in the series have about Seimei.
