Subaru was the guy in the white robes in the first 
battle I believe.  Unfortunately, finding cels of him 
will be REALLY hard.  As stated in the previoius post, 
he only appeared for a couple minutes.  Also, even 
though he is in Tokyo Babylon, Subaru is a fan favorite,
 and rabid TB fans snatch up cels of him extremely 
quickly, so it's very difficult to find cels of Subaru.  
He looks pretty nifty in that white outfit during the
 movie though.
