You were interested in my avatar? (Sorry, I haven't come onto the forums in For-EVER, so I have had no idea of any happenings, really.)
It stems from a game called Elsword, it's a 2(.5)d beat-em-up style game. The character is Rena - more specifically the "Wind Sneaker" class.
It's a really fun game if you can get into it, I assure you.
