Trivia

 * This does not relate to any of the six series being canon, with several references from many FanFiction projects.
 * FanFiction characters from Superior-Creativity's Saint Seiya Omega like Apus Sachi and the major Venusians, will be in the story.
 * There is a new ability that will be major to the Haikyū!! series in this crossover: almost all Haikyū!! characters will wield ninja weapons and use the art of ninjutsu. Some of the series' characters can use unique powers like the elements, etc.
 * For the Haikyū!! Dub Cast, Bryson Baugus, Brittney Karbowski, Adam Gibbs, Greg Ayres, Rebekah Stevens, David Wald, and Chris Patton will respire their respective roles, while the rest of the cast get LA voice actors to save time and money for Sentai voice actors that haven't done work in LA or in English Dub video games.
