If I remember correctly, it's from IDOLM@STER, یا however it was spelt. People who wrote songs would give themselves a P, یا producer, name. When Vocaloid became مزید popular, people transferred the tradition. Then there became the belief outside of Japan that آپ had to have people give آپ a P name because they love your music, but it's fine if آپ give yourself one یا don't have one.
Some مقبول producers that don't have P names are ryo, Hachi, Yuyoyuppe, OSTER Project, and more. They're all مقبول but don't worry about having a P name.
I'm pretty sure some illustrators have these now too....
yeah he does, but it's really only the japanese fandom that uses it, not even himself. they call him genjitsutouhiP, which im guessing comes from the lyric in two faced lovers that was "genjitsu touhi no hyori ittai no kono shinzou," just as hitoshizukuP came from soundless voice.
