Trivia

 * Ibuki seems to have great interest in baseball, specifically the Japanese Yomiuri Giants, as the score "55", the sfx of "Goji", the outcry of "Roda(m)n!" and other number scores all relate to Hideki Matsui, also known as "Godzilla" and an all-star MVP.
 * Gina's and Akemi's appearance with a painted face and star over their eye is a reference to Kiss' guitarist and vocalist Paul Stanley or "The Starchild." He's especially well-known for a wide-ranging voice.
