Asuka (飛鳥 Asuka) is a concept character who was originally going to be in Street Fighter V. She was going to fight using Aikido. The reason she got scrapped was due to the fact that there are too many Japanese characters.
Asuka is a young Japanese woman who has long black hair. Both of her concept designs have her wearing a black hakama and wearing no shoes. In her first concept art, She wore a white headband with a red circle in the center to represent the Japanese flag, black wristbands, and a white sarashi that covers her chest and breasts. In her second concept art, She sports a different hairstyle and also wears a long-sleeved gi with a black undershirt on underneath. A small picture on the right shows her wearing an Oni mask.
Asuka would've been an Aikido practitioner that used her opponent's strength against them.
