下剋上(完) (Gekokujou (Kan))

Background
Gekokujou/Gekokujō is a Japanese term variously translated as the lower rules the higher or the low overcomes the high. In this song, more commonly known as Revolution (End), the Kagamine's sing about supplanting Miku as #1. A fun, upbeat rap song, this is a must for all the hardcore Kagamine fans.

The main idea involved is the Kagamines attempt to prove that they can surpass Miku. The course of the song is packed with the confidence of the Kagamine duo, many compliments of their skills and traits, and a considerable amount of thanks to the audiences, as it sheds its dose of humor in various occasions.

On 2011 it became one of the Kagamines' Append demos for all the voices of the Appends (Rin and Len power Appends as the main, with warm, sweet, cold, and serious as backups)
