When an effort to assassinate Ayanami, a high-ranking official who killed his father, fails, Teito is locked away awaiting punishment.
Only wanting the simplest for Teito, Mikage helps him escape. Teito finishes up at the 7th District Church where he’s taken in by the bishops. it’s here that Teito attempts to evade the grasp of Ayanami and therefore the Military, so he can rediscover his memories and learn why he’s the person who can change the fate of the planet.
