I read the manga till chapter 16. The story is a lot different from Lelouch of the Rebellion (anime and manga of Lelouch of Rebellion are also different!). So it's the story following Nanally and she obtained the power from Nemo.
I have this question... what is Lelouch doing? I read in chapter 10 that he met Prince Schneizel. And Lelouch is addressed as "his highness" so is he back to the Britannian empire? I have lots of questions to this manga. I think I understood Nanally's part but I want to know more about Lelouch's part in the manga.
So... let this thread become also a discussion for the manga Code Geass: Nightmare of Nanally. I want to see you views of this manga.
