円舞曲、君に (Enbukyoku, Kimi ni, "Waltz, to You") is the theme song of the Sakura Taisen: Kanadegumi (サクラ大戦奏組) manga, a spinoff of SEGA's Sakura Wars franchise that breaks from tradition by centering on an all-male ensemble of musicians rather than the series' usual all-female combat troupes. The title itself signals its musical identity, 円舞曲 (enbukyoku) is the Japanese term for a waltz, and the lyrics, penned by franchise co-creator Oji Hiroi (広井王子), weave together themes of protection, passion, and the blooming of sakura through the power of music. Composed by longtime Sakura Wars veteran Kohei Tanaka (田中公平) and arranged by Takayuki Negishi (根岸貴幸), the song is performed by the Imperial Flower Brigade / Kanadegumi (帝國華撃団・奏組), a vocal unit of five prominent voice actors: Yoshimasa Hosoya (ヒューゴ・ジュリアード), Satoshi Hino (G.O.バッハ), Yoshitsugu Matsuoka (桐朋源二), Yuki Kaji (桐朋源三郎), and Shinnosuke Tachibana (フランシスコ・ルイス・アストルガ). At 128 BPM in a stately waltz tempo, the track layers choral harmonies over orchestral pop instrumentation, capturing the theatrical, romantic spirit that defines the Sakura Wars franchise. In maimai, 円舞曲、君に debuted on July 11, 2013 as part of the GreeN edition's launch lineup, initially locked behind a 10,000 maimile purchase before becoming default-unlocked from the ORANGE update onward. Its MASTER chart (level 13, constant 13.3) was crafted by designer はっぴー, while the EXPERT chart (level 11) was handled by ニャイン, both longtime contributors to maimai's earliest song catalogs. Over the game's version history, the song's difficulty levels were rebalanced multiple times to keep pace with maimai's evolving difficulty curve.
