It's a year after the battle between the Black Knights and the Britannian army. Zero is dead, and only a handful of Black Knights remain. But Lelouch is alive with no memory of the last year. Is it a trick or all part of a greater plan?

Lelouch tries to get clues about Nunnally's whereabouts, but no one around him remembers her. To find her, he'll have to figure out his mysterious new brother, Rolo. But he'll have to do it while maintaining the guise that his memory hasn't returned.
