SPICY SWINGY STYLE is a high-tempo pop track belonging to the Irodorimidori (イロドリミドリ) multimedia project, performed as the second solo song for the character Serina Akesaka (明坂 芹菜), voiced by Emi Nitta (新田 恵海). The song was composed and arranged by Jesahm (BNSI) with lyrics by Hiroyuki Onoda, and its music video was produced by 鑓田 (alpha complex). Clocking in at 242 BPM and roughly 1:54 in length, the track carries a buoyant, swing-infused energy that matches its title, a "spicy" rhythmic drive layered over a pop framework. The song first debuted in SEGA's CHUNITHM AIR PLUS on June 22, 2017, before crossing over to maimai as part of the MiLK update on December 26, 2017. In maimai, it initially carried the ORIGINAL & JOYPOLIS genre label before being recategorized under ONGEKI & CHUNITHM from the DX PLUS era onward. Its Expert chart, designed by 某S氏 (Bou S shi), and Master chart, designed by 小鳥遊さん (Takanashi-san), have both seen level adjustments across versions, the Expert chart rising from an initial level 10 to its current 11+ (11.6 constant), while the Master chart settled at level 13 (13.4 constant). For Asian English releases of maimai, the artist credit is localized to "Serina Akesaka (CV: Emi Nitta)."
