Yes! She appeared on this special live (or whatever it is called) for the Light Lag release. Here’s a screenshot of her:
You’re very welcome. ♥
more Vocaloid-Ps are being hired to do professional work!
kz and DECO*27 will both be contributing a song to KOTOKO’s next album.
02.☆-未来-列車-☆ (☆-Future Train-☆)／ 作詞：KOTOKO 作・編曲：Kz : sample
03.メーテルリンク (Meter Link) ／ 作詞：KOTOKO 作・編曲：DECO*27 : sample
But they’re not the only ones that KOTOKO has her eyes on! Supercell is also going to be working with her to create the OP song for Shakugan no Shana -Final-. (source)
I don’t really like her voice in kz’s song but DECO’s song sounds pretty solid. Both are pretty typical kz-style and DECO-style songs.
