We’ve posted about Zero-G‘s new VOCALOID Avanna before but now it’s time for what we’ve all been waiting, a demo of her singing and her character design. At NekoCon 15, a sneak peek of Avanna singing was demoed at the convention’s VOCALOID panel after the VocaNoIro concerts. The audio track, a cover of Enya’s “Only Time”, used an early beta version of Avanna and is intended to be a sneak peak only and not a finalized demo. AkiGlancy (Empath-P) was also revealed to be the illustrator for Avanna via the Avanna Fan-Club at deviantART. The design was commissioned in early August by Zero-G and went through several revisions based on feedback from Zero-G as well as Yamaha. A finalized draft was requested at the end of October, and Zero-G scheduled for a release of the box art today. A few images of Avanna are now available on AkiGlancy’s deviantART gallery, and a mockup of the box was posted to the official Avanna Twitter account (@vocaloidavanna) as well as the official Facebook page and official website. The relevant thread on VocaloidOtaku contains more information about the design process and trivia.
