"創聖のアクエリオン" (Sōsei no Aquarion) is the opening theme of the 2005 mecha-anime series Genesis of Aquarion (創聖のアクエリオン). The maimai version is credited to AKINO［cover］— the same vocalist who originally performed the song for the anime, here delivering a game-specific recording. The track arrived in maimai during the GreeN edition (released July 11, 2013) under the POPS＆アニメ genre (categorized as アニメ prior to the ORANGE PLUS update). It was later removed from the arcade lineup on June 30, 2016, making it one of the early deleted songs in the series' history. The song is known for its soaring, dramatic melody and the repeated refrain of "愛してる" (aisuru / "I love you"), which became a widely recognized hook in Japanese pop culture. Notably, as the Japanese wiki observes, many Japanese players encountered the track not through the anime itself but through looped pachinko-machine commercials that used the song, giving it a distinctive second life in the public consciousness. In maimai, the Master chart (level 10, designed by はっぴー) stands out for its dense Slide-note patterns, 109 out of 341 total notes are Slides, an unusually high proportion for a GreeN-era chart and a hallmark of the designer's style.
