Appearance
She originally appeared with the outfit used for Candy Rock Star, a 3D "live performance" using Unity technology. In the Candy Rock Star video, she performed "UNITE IN THE SKY!" a song featuring her voice provider singing as Kohaku.

Her original debut outfit consisted of a blue long-sleeved shirt with a brown and orange vest over it. The vest had orange checkers on the side, with the word "Unity" under it. She also had orange striped thigh high socks and black shoes. Her hair was split into a sort of twin tail style.

Her VOCALOID design is a twist on her original debut outfit, but with major changes.

In all of her designs, she wears her signature black headband with long orange ribbons attached.

Marketing
Originally, assets for her were downloadable for free to work with the Japanese version of the Unity engine. This proved a popular move with developers using the product.

Her license was set to be modified in line with her Vocaloid release. For use of her voicebank within projects, for the non-upfront cost of 10 million Yen the voice will be provided (10 million is the consultation cost) with no additional charges. For other public use of the voicebank, a Vocaloid engine fee will have to be paid. This is due to the Yamaha royal system, and users will have to seek consultation with 3rd parties for use with Vocaloid and other company's vocals (example Crypton Future Media, Inc. and Hatsune Miku).
