Elecman.exe is awesome! I love his design too! In the anime, Gemini Spark 2 entities were basically Gemini and Tsukasa/Patrick, his human host. In the games, though, Gemini Spark was Tsukasa and his evil split personality Hikaru/Rey. He was compatible with Gemini due his split personality and when they wave change, gemini gives a body to both of them... and both Gemini and Hikaru convince Tsukasa to do evil stuff.
Its funny to see how in the anime Tsukasa forgets about all what he did (and dont get me wrong, he DID all the evil stuff with gemini) once gemini is gone XD. In the game, though, he keeps on having the wave change power and that gives him trouble when Hikaru wants to go out to play XD.
I am not profesional and I sell the books only in conventions and in the net, I dont have an editor, I just make the books and order them to be printed ^^. But for printing I use printcolor, I think its an only spanish site, though
