Google and Youtube aren't helpful, so I'm asking here. Does anyone know where this comes from?

Where did you find it?
And its Len Kagamine btw

A Youtube user called Fairuzons had it on his account (which got suspended a few years ago). I wrote a PM to his Alt (fairuzonss), but he never responded and also got banned too. His third account (fairuzonsandfriends) is inactive since 2 years. I converted the MP3 with YoutubetoMP3, but unfortunately it is the only song I've got from him.

Thanks for the hint with Len =)
