Can-can ~Orpheus in The Party Mix~

The track is built on the closing galop from Offenbach's operetta Orpheus in the Underworld, one of the most instantly recognizable tunes in popular classical music. Although it took first place in the 2018 contest, it drew heavy criticism within its own batch: released alongside the second- through fifth-place entries, many players felt it fell short of what a winning song should be, with the common complaint that it amounted to little more than the classical original with a drum beat layered on top.

MiLa's BGA also fed the criticism, partly for poor readability. It features a five-member sentai-style hero team who are actually recycled protagonists from other songs' BGAs, namely Elysium, Utsushiyo no Kaze, the archer from Silhouette Effect, Just hold on, and Arcana Force. Earlier MiLa works scroll by in the background, including the recurring pig villain, and it closes with a space-shuttle launch and an "adios!" card. The crossover fueled the long-running fan theory, treated here as an indirect confirmation, that MiLa and Felnya are the same person.

Alongside the normal Single charts (S8/S13/S16/S19/S22), the 1.05 update added a Short Cut made up entirely of Double charts: seven odd levels from D13 to D25, making this the first song to debut with no Single chart. Its D13 floor means pure Single players cannot jump straight in. The D23 left a strong impression in the teaser with its splits and twitch patterns, earning the nickname "Kangkang dakba," though its short length keeps it relatively manageable. The D25, plastered with huge staircases and capped by a final hold note worth roughly 700 combo, was the first level-25 Short Cut chart.
