THE VOC@LOiD M@STER is one of the biggest amateur Vocaloid only events in Japan. The monumental 20th event will be held at Makuhari Messe in Chiba, as part of the mega festival "Nico Nico Cho Kaigi", on April 28 and 29. 618 Vocaloid doujinshi and music circles will participate, and of course a tremendous number of Vocaloid cosplayers will be there for fun. The number of the circles is highest ever for the quarterly event. As usual, many circles have already posted promotion videos for their songs on YouTube. Which is your new favorite Vocaloid song?
