Fukase is based on Fukase so I pretty much said the answer when I said Fukase is based on his provider's natural tone.

In short... The real singer was singing before he made the vocaloid, he made it more as a audio aid hence why it has English. We don't know all the details beyond this like why it was decided to sell it and not keep it private but... It doesn't matter.

If none of this is the correct answer, you might have to re-word your OP.
