What is the background story of Hatsune Miku?


I do understand it is a fictional character, and so I feel there must be a
story behind this virtual Diva. I am interested in learning "how" Hatsune Miku
became interested in singing.




As is the case with most vocaloids, the company that invented 初音ミク (Hatsune
Miku), Crypton Future Media, released an [official personal data
sheet](http://en.wikipedia.org/wiki/Hatsune_Miku#Characteristics) for Miku;
however, this contains her physical and technical traits rather than
personality or back story, which intentionally allows the [fans to take a
role](http://www.crypton.co.jp/download/pdf/info_miku_e.pdf) in developing the
characterization of the character. She is referred to as a "beloved
[collaboratively
constructed](http://www.crypton.co.jp/mp/pages/prod/vocaloid/cv01_us.jsp)
cyber celebrity with a growing user community across the world." Some fans
have been allowed to create officially-sponsored costumes for Miku through a
[design
competition](http://en.wikipedia.org/wiki/Hatsune_Miku#Winter_festivals) for
the Sapporo Yuki Matsuri (Snow Festival). It could be said that the clothing
design becomes a part of the character's personality (i.e. this is the sort of
fashion that Miku would wear).

[『メーカー非公式
初音みっくす』](http://en.wikipedia.org/wiki/Hatsune_Miku:_Unofficial_Hatsune_Mix) (
_Meekaa Hikoushiki Hatsune Mikkusu_ ) is a manga about Hatsune Miku which ran
in『月刊コミックラッシュ』( _Gekkan Comic Rush_ ) magaizine published by ジャイブ株式会社 (JIVE
Ltd.). It is licensed in North America by Dark Horse Comics under the title
_Hatsune Miku: Unofficial Hatsune Mix_.

[『週刊はじめての初音ミク』](http://ja.wikipedia.org/wiki/%E9%80%B1%E5%88%8A%E3%81%AF%E3%81%98%E3%82%81%E3%81%A6%E3%81%AE%E5%88%9D%E9%9F%B3%E3%83%9F%E3%82%AF)
( _Shuukan Hajimete no Hatsune Miku_ ) is a _yonkoma_ gag manga that ran in
『週刊ヤングジャンプ』( _Shuukan Young Jump_ ) magazine published by 集英社 (Shuueisha).

Additionally, some mangaka of 『りぼん』( _Ribon_ ) shoujo manga magazine published
by Shuueisha have drawn [illustrations of Miku](http://mantan-
web.jp/2015/05/01/20150430dog00m200029000c.html) that were included in a 付録
(furoku = freebie) included with an issue of the magazine, and on some special
pages printed in the magazine.

Each of these portrayals have different aspects and storylines for Miku, in
keeping with the collaborative, undefined nature of vacaloid characters. There
is no one background story for Miku. Crypton intentionally encourages fans to
create their own songs, music videos, visual novels, doujinshi, fanfiction,
fanart, etc. and basically anything is fair game; portrayals that strike a
chord with many fans rise in popularity, where fans adopt another fan
creator's rendition of Miku into their own image of her character. Miku is who
each person wants her to be, which includes limitless options for coming up
with her backstory.
