Nightmare of Nunnally

About
Code Geass: Nightmare of Nunnally is one of the three Code Geass manga. (The other two being Lelouch of the Rebellion and Suzaku of the Counterattack). In this spin-off, Nunnally is the main protagonist instead of Lelouch and it depicts what would happen if Nunnally got a Geass instead of Lelouch. It is not connected with the Televison version.

Plot
It begins just like Lelouch of the Rebellion, with Lelouch gambling with chess and beating a Britannian Noble. Shortly after, Nunnally calls him reminding him about a promise he made to her earlier. He tells her he'll be home quickly by going through the Shinjuku_Ghetto. Nunnally warns him not to but he calls it a "regular shortcut" and hangs up. Rivalz leaves him and Lelouch remembers his promise to Nunnally which he made the day before.

While walking through the Ghetto, Lelouch barely dodges a truck with bullet holes in it. The truck crashes and Lelouch quickly goes and checks on the driver. The driver mummbles something about the cargo and the capsule comes out of the back. The capsule opens revealing C.C and a doll. Lelouch quickly runs to C.C. but Jeremiah and other Knightmare Frames come. Clovis, now seeing that C.C. is out of the capsule and some of the Elevens may have seen her and gives the order to obliterate the entire ghetto. He fires a missle at the Ghetto. Lelouch tries to escape in time but while running a massive pilliar falls towards him. As is it going to hit, the Geass mark on C.C. head and on the doll begin to glow. After the area is destroyed, Britannian news reports that terrorists have destroyed the ghetto. Nunnally then claims someone is calling her and leaves before Sayoko Shinozaki comes for tea.

After the explosion, a member of the Purity League comments of the events the recently happened calling them 'cruel'. Villetta quickly repremands him and tells him to delete the comversation from the memory.
