Hachune Miku (はちゅねミク; Miku Hachune) is recognized as a famous official derivative of Hatsune Miku. Hachune (はちゅね) is a mispronunciation of Hatsune, which shows her childishness and generally silly disposition. She is often seen in videos as a blank-eyed doll-like figure with a gaping mouth.
The term "Derivative" is used here to describe a fanmade Vocaloid character that is based on an already existing character.
Hachune Miku was created by Otomania (video) and Tamago (picture) and established via Hatsune Miku's version of Loituma Girl internet meme, eventually going on to becoming its own character. Miku Hachune is acknowledged as one of the first mascots to gain popularity within the Vocaloid fandom.
Hachune Miku is one of the Vocaloid derivatives that became officially recognized by Crypton Future Media, the publisher of the Character Vocal Series for VOCALOID2. The other derivatives bearing this distinction is Meiko Sakine, Neru Akita, Haku Yowane, and Tako Luka.
Official licensed Hachune Miku merchandise has been produced, such as Nendoroid Puchi and plush toys, key chains etc. The Hatsune Miku Nendoroid figure that comes with a face representing Hachune, while a limited edition Nendoroid of Hachune was also produced by the Good Smile company at the Wonfest 2008 Summer fair.
In Maker Hikōshiki Hatsune Mix, Hachune Miku often appears out of nowhere making cameos, upsetting the main characters and generally getting herself into trouble. She appears in chapter 2 and chapter 3.
Hachune Miku no Nichijō Roipara!, a manga drawn by Ontama began serialization in the manga magazine Comp Ace on December 26, 2007. See Otomania.net: はちゅねミクの日常 ろいぱら！
In Project Diva (PD), Hachune Miku makes a cameo in the PSP game, Hatsune Miku ~Project Diva~ and again as a playable character in its sequel (end credits and tutorial mode only).
- Despite fan belief, she is not actually holding a leek, but a Welsh/green/spring onion (negi, or 葱).
- Hachune is responsible for the start of the Item War system that eventually began ending with the entry of Tako Luka later on.
- In music videos and songs that have a singing voice in them, the voice is more of a representation of Hatsune Miku, rather than her actual voice. She is regarded a silent mascot by the fandom. However, her voice can be heard in Project DIVA extend's opening (the version with voices).
- Often, it's exactly the same as with Hatsune Miku. Though, she is intended primarily as a mascot, rather than a singing derivative.
