In a 2010 interview with the game's producer Yoshinori Ono published in the MTV Multiplayer Blog, before the release of Super Street Fighter IV, he revealed that he's a big fan of the character Rainbow Mika, and that he wanted her to be put in Street Fighter IV, especially in Super Street Fighter IV. He "basically harassed the director constantly" by just whispering in his ear "Rainbow Mika! Rainbow Mika!". Ultimately, the directors of either version of Street Fighter IV didn't listen to Ono for unknown reasons, and Rainbow Mika never appeared in any Street Fighter IV installments. She would later appear as a playable character in Street Fighter V.
