回レ！雪月花 (Maware! Setsugetsuka) is a high-energy J-pop track composed by Hige Driver and performed by the unit 歌組雪月花 (Utagumi Setsuketsuka), which brings together the three main voice actresses from the anime Unbreakable Machine-Doll (機巧少女は傷つかない): Hitomi Harada as Yaya, Ai Kayano as Irori, and Yui Ogura as Komurasaki. Originally released as the ending theme for that anime in 2013, the song made its maimai debut in MURASAKi on December 15, 2016, and later received a full set of DX chart revisions when maimai でらっくす launched in July 2019. The title translates to a spirited command, "Spin! Snow, Moon, Flowers", blending a festival-like call to dance with 雪月花 (setsugetsuka), a classical Japanese poetic phrase that evokes the beauty of the changing seasons. The lyrics are dense with kabuki-inspired four-character idioms (yojijukugo) and playful theatrical chants, building toward the infectious chorus "Maware maware maware maware!" that gives the song its signature energy. The result is a carnivalesque atmosphere that mirrors the steampunk-meets-traditional-Japan aesthetic of the anime it accompanies. Due to licensing restrictions, 回レ！雪月花 is exclusive to Japanese cabinets of maimai, though for a brief window from December 2016 to January 2017, overseas players could access it through a limited-time Event Course (てーきゅう コース), the only period it was ever playable outside Japan. Beyond maimai, the song appears in SEGA's other rhythm games CHUNITHM and オンゲキ, making it one of the most cross-licensed anime tie-in tracks in the company's catalog. In maimai, both the Standard and DX chart sets offer distinct experiences: the Standard Master chart (designed by rioN) presses players with dense Tap streams, while the DX Master chart (designed by 華火職人 / Kanon Oguni) makes heavy use of the DX cabinet's Touch panel with 128 Touch notes woven into its layout.
