Although Gakupoid was originally set for release on June 2008 with Gackt as a model for the Vocaloid, its illustrated avatar was yet to be determined. Popular manga author Miura Kentarou of Berserk was finally asked to do the illustration, and due to his affection for Nico Nico Douga, he actually offered his services as a character designer for free. Gakupoid was thus released with Kamui Gakupo on the 31st of July 2008.
Awesome cosplay! And very awesome of the mangaka to create such quality work for free. Thanks to Kei for suggesting this!
