This is the first single to be released since they started live performances. As soon as the kazoo tone that heralds the beginning of the world stops playing, the rational rap of Yamaguchi and the passionate scream of Hayata intersect. Then, after passing through the chorus, where everything seems to blend and unravel, a development that makes the floor fall out awaits. This is a song that invites the listener to the blackness that lurks within the self-consciousness, and to the extreme colors that lie even deeper within it.
