VocaCircua is a YouTube channel that uses mainly Luka and Gumi. They have composed some of Luka and Gino's most popular like Lie, Circus Monster, Echo, and Wildfire.

On April 1, 2015, they posted the song Game Master. Game Master has about five seconds of actual song. It then switches to a thirty second rap by Kai Yuuki and someone else *Whose name I honestly don't know* about how you just got trolled. For the rest of the four minute, twenty one second video, Kai Yuuki and other stay there with the troll face.
