Yeah, Sanger's Gilgamesh. Though, if Ryusei were a Servant he'd be almost anything

Heck, it could even be a line to stick into a pure SRW fic.
As for that NGE/SRW crossover, I saw the thread, and check it with near-rabid enthusiasm. But, until I actually get off my ass and play the rest of the way through the games, I won't really be in a position to offer any intelligent commentary, just 'MOAR' and finding that 'I like where this thread is going' picture to link.
Though, being as I am a Lat fanboy, I will offer total homage towards your current course, and beg you to focus upon it
