Now known as Zero, the masked terrorist has held a crowd hostage, taken responsibility for killing Clovis, and broken Suzaku out.
But when asked to join him, Suzaku refuses. He'd rather make Britannia worth from inside than destroy it. He turns himself in for his court martial.

She calls herself only by her initials, C.C. She moves herself in with Lelouch and his sister and starts wandering around the school.
