World's End Dance Battle

Here is a visual feast throughout, from when Miku's group takes on Luka's (and although it's close, if you study it closely, Luka wins narrowly, I think) to when they shake hands and join up, the dragons and more besides. The outfits are sumptuous, the movement is superb (especially Luka) and the settings are brilliant, especially the Downtown street scene with the 'Hotel Gorgeous' (I kid you not).

The song is the ever-excellent World's End Dancehall by wowaka, and this video – which comes from the Project Diva f game – has rightly been classed "a masterpiece" by at least one commenter...
