Cera, an up-and-coming rapper who boasts high popularity among young people mainly on SoundCloud, has invited rapper Yay boop, who became a hot topic with his song "E-girls," to perform on his first single. This fresh sound mixes elements of Hip Hop and Chill Phonk, which is unique in Japan, and the inorganic yet addictive voice and flow of Cera and Yay boop are a must-see.
