The mascot of the software is called Camui Gackpo (神威 がくぽ, Kamui Gakupo), after Gackt's alias name.

The name "Gackpoid", meaning "Gackt-like Vocaloid", was chosen by Gackt himself during the voice recording process.

[11] Gackpoid V4, an update to the voice library using the Vocaloid 4 synthesizer software, was released on April 30, 2015.

Gackpo is designed to resemble a samurai clad in a jinbaori, a type of kimono which was used as a battle surcoat along with parts of traditional armor, while carrying a katana.

[17] Gackt promised viewers that he would choose one or more of the winning songs to cover for eventual recording and release.

[18] The official winning entry was declared to be Episode.0, by mathru/Kanimiso-P, during the “NicoNico Daikaigi 2011 in Taiwan” event, where Gackt announced that Episode.0 and another finalist, natsu-P's Paranoid Doll, had been covered by him and would be released together as his thirty-ninth single.
