YM

1) YM is a producer who rose to popularity when his song "Ten-Faced" was released. His work has since appeared in the VOCALOID-P data series. He exclusively uses GUMI but sometimes also sings songs by himself. 2) "Atop the cold, stone spire enshrouded by frozen winds above the Alpen Peak, Ym spins the omnipresent arcane threads into great works of myth and legend. However, in his free time, he scribes small tomes accounting various journeys." https://ymthecosmic.bandcamp.com/
