I was going to dye my hair purple to cosplay Fujiwarano Sai (Hikaru no Go), so I started looking for other purple-haired characters I could cosplay in the same convention without changing my hair... a girl in my cosplay forum suggested Athena, and since I'm a big fan of fighting games, and her costume was easy enough, I liked the idea (at the end, my hair didn't become very purple ^^U but I still enjoyed being Athena)
