Dive into The Sky ～initialized～ is a Eurobeat arrangement of the Touhou Project track 風神少女 (Wind God Girl), the photo-theme music from 東方文花帖 ～ Shoot the Bullet (2005). The arrangement was produced by the doujin circle A-One, a group well known in the Touhou arranger scene for its high-energy Eurobeat and hardcore dance sound. The track originally appeared on A-One's 2008 album KARMA SCREEN, where it was arranged and lyrically penned by ELEMENTAS and sung by longtime Touhou vocalist Nana Takahashi. ZUN's original composition serves as the melodic foundation, given a fast, driving Eurobeat treatment at 165 BPM. The song joined the maimai DX song library during the Splash era, arriving on February 5, 2021 for Japanese arcades. The Expert chart was designed by はっぴー (Happy) and the Master chart by 小鳥遊さん (Takanashi-san). The Master difficulty notably underwent a level re-rating over its life: originally set at level 12+ (roughly equivalent to a 12.7–12.9 constant in the DX system), it was bumped up to a full level 13 beginning with the FESTiVAL version, reflecting the chart's sustained technical demand relative to the evolving difficulty curve. The MASTER chart features a dense 770-note layout with a notably high Break-note count (39) for its era, giving it a distinctive scoring profile among Splash-era Touhou charts.
