Ok. v4 Flower got a live. Kotonoha Akane and Aoi also got to be in NicoNico Cho Party. They did not sing their original songs. If THEY can do that, Fukase can. Fukase has an amazing voice and he was great original songs too.
It only makes sense for him to join in NicoNico Cho Party. And the company that made him does not matter; Yamaha made him, and Yamaha made Flower too (who got a live).
AND Teto, who is a UTAUloid and NOT a proper VOCALOID got a live too. If an UTAUloid gets to be in NicoNico Cho Party, so does Fukase, and many other VOCALOIDS such as YOHIOloid, Piko and Oliver.
