This is the artwork from the new Days of Memories game. I've tagged it as such. The girl with purple hair to Athena's right is Hatsushiro Athena - she's Athena based on her appearance in the original "Athena" game. (I added a tag for her name, too.) I don't know Japanese well enough to be able to tell you how they work this in the game, but here's the site with a little bio of some sort, if anyone cares to shed some light on the situation: http://game.snkplaymore.co.jp/official/dom/original/index.html
