A.K.A.: Aya-tan (by Hyuuga)

The main antagonist. He is the man who killed Teito's 'Father' in the war against Raggs and seeks the Eye of Mikhail. It is known that he was born in to a family of nobles, but prior to the series they were cast out from the royal line for a yet unknown reason. Some elder officers mock Ayanami and his family for that and they tend to make things difficult for him. It is most likely that they are jealous of him due to the fact that he outranks them at such a young age, as they use phrases such as a 'brat', 'impertinent youth' and 'intolerable youngster' to describe him.
