Teito is caught eavesdropping and tries to attack Ayanami but is quickly brought down by one of his subordinates and sent to prison. Mikage comes to help him escape, only to find that Teito has managed to fight past the guards by himself. The two flee the building but are cornered on a balcony. Teito pretends to hold Mikage hostage, then makes his escape, though he is wounded by a Zaiphon blast that Ayanami directs at him. Three bishops in the nearby 7th District discover the injured Teito and take him to a nearby church to recuperate, where he is protected because of the 7th District's law of sanctuary.
