Phew. OK, I think I've got everyone tagged who wasn't already. The only one I'm not 100% sure on is the one to the left of Hibiki; I think, based on her hair length, that it's Miyuki, but I can't really tell most of Fubuki's sisters apart. There are some duplicates (Fubuki, Sendai, Hiryuu, Soryuu, are all present twice for no reason I can readily discern). No idea why "cypher" was tagged as a character, so I removed that one.
I can't be arsed to go through and tag everybody's hair color, eye color, type of clothes and so on. I leave that for someone more obsessive than me. :)
