Scenario writer, Akihiko Ureshino, states that the Meira siblings became twin brothers to avoid comparison with other brother characters from other SNK games, such as the Kazama brothers from the Samurai Shodown series and the Jin brothers also from Fatal Fury. He also addresses that the main complaint received from fans was concerns of the brothers "not looking alike"; in response, Ureshino admits that he was also unaware of Alba and Soiree being siblings until much later in production and shares his confusion with fans.
