Miku! Miku!

Vocaloid is a singing synthesizer application software developed by the Yamaha Corporation that enables users to synthesize singing by typing in lyrics and melody.
Hatsune Miku (初音ミク) is the first installment in the Vocaloid2 Character Vocal Series released on August 31, 2007. The name of the title and the character of the software was chosen by combining Hatsu (初, First), Ne (音, Sound), and Miku (未来, Future)^. The data for the voice was created by actually sampling the voice of Saki Fujita, a Japanese voice actress. Unlike general purpose speech synthesizers, the software is tuned to create J-pop songs commonly heard in anime, but it is possible to create songs from other genres.
The character's first appearance in an anime is in (Zoku) Sayonara Zetsubō Sensei, where she (and various other people and characters) try out to be the voice of Meru Otonashi. For online multi-player games, the Japanese version of PangYa started a campaign with Hatsune Miku on May 22, 2008 in which a player could purchase her outfit for one of the characters. Her first appearance in a video game is in 13-sai no Hello Work DS (13歳のハローワークDS) for the Nintendo DS where she is included as one of the characters. Hatsune Miku was given a PlayStation Portable game called Hatsune Miku: Project DIVA that was released on July 2, 2009 by Sega. Hatsune Miku made a cameo appearance in the Lucky Star OVA in the form of Kagami's cosplay in her dream. She made a vocal appearance in the finale ending theme of the anime Akikan!. Hatsune Miku received the 2008 Seiun Award in the free category.
 As a virtual idol, Hatsune Miku performed a "live" concert during Animelo Summer Live on August 23, 2009 and at Anime Festival Asia (AFA), Singapore in 2009. In addition, singer Gackt performed alongside Miku.

An all new perpective of Miku!
A collaboration between the popular illustrator Nagimiso and Max Factory brings a figure of this cybernetic Miku, which was originally illustrated by Nagimiso as a character for the VN02mix of Miku Hatsune's original song 'moon'.

Placed in an elegant pose as if soaring through the air, this version of Miku is far more than just a robotic version of Miku, it's a carefully designed decorative masterpiece - a bold, yet finely crafted figure that will suit virtually any collection!
