Akira Kazama is one of the Rival Schools and Project Justice Characters.
She made her debut in the arcade version of RS back in 1997 and is playable in two forms, her normal clothes and her motorbiker suit with a few slightly different special moves. She uses mainly Tai Ji Quan as her fighting style with the addition of someTaikyoku-ken movements. Akira is the younger sister of Daigo Kazama, and a pretty badass girl. She was supposed to be a character in the cancelled Capcom Fighting All-Stars fighting game.
There are relative many official artworks of her and also some beautiful fan art and cosplays too, some even from 2013 which is pretty cool considering how old and quite unknown Akira Kazama is.
These four images are loading screens in Rival Schools which can be unlocked there.
