Prismatic is a high-energy Touhou Project vocal arrangement by the doujin music circle CielArc, based on Cirno's iconic stage-boss theme おてんば恋娘 (Beloved Tomboyish Girl) from 東方紅魔郷 ～ the Embodiment of Scarlet Devil (2002). The arrangement credits M×R×I for the instrumentation, with Yuzuri handling both vocals and lyrics, and additional bass arrangement by 深澤いたる. Released originally at Comiket 92 (August 2017) as part of a self-titled doujin CD, the track sits at a brisk 180 BPM, a fitting tempo for the ice fairy Cirno's mischievous, playful character. The jacket illustration was drawn by 白蜜柑, with logo design by さなぎ. Prismatic joined the maimai song library as part of the 東方Project category in maimai でらっくす Splash, arriving on February 5, 2021 in Japanese arcades and later rolling out to international and Chinese cabinets. Its MASTER chart (level 12.2, designed by はっぴー) offers a dense but accessible 750-note layout with prominent Slide and Touch patterns, while the EXPERT chart (level 9, designed by 某S氏) tests intermediate players with its heavy Hold-note presence. The track remains available across all regions and has not been removed from rotation.
