ハッピィハロウィンミュシカズ (Happy Halloween Musicas)

Background
There is a rumor of the happiest, most dangerous "musican group" that on the night of halloween, appears out of nowhere

The song is sung from the point of the "Halloween Musicas", a group which consists of six musicians doing five diffrent styles that entertain people on Halloween, killing them and bringing them back to life. The group consists of the Idol Musica (Miku), the Metal Musica (Luka), the EDM Musicas (Rin and Len), the Jazz Musica (KAITO) and the Ethnic Musica (MEIKO). In the end, they depart without an encore, promising to return next year for more.

The Musicas represent each diffrent style Machigerita-P has done in the past.
