In case you don’t know. Vocaloids are computer synthesized voices. Strange and beautiful at the same time.
“Keina Suda, also known as the Vocaloid producer Balloon, is ready to contribute music to the popular mobile game Project Sekai: Colorful Stage! The creator initially began making Vocaloid music back in 2013, and his hit song Charles has been covered by many other singers.”
