I am getting back on my anime/manga life (yes, finally!) and I started catching up with Code Geass: Shikkoku no Renya. I am really glad I started with this because finally, a full shot of what seems to be Lelouch is being shown. This is from Chapter 5, and it has been made clear that C.C also knew this person.
However, his name is not yet revealed and as I patiently wait for the scans, I think I'm gonna ask for public opinion.
