Lily originally appeared on the cover of the CD "anim.o.v.e. 01" released on Aug 19th, 2009, before the announcement of her VOCALOID development. Lily was introduced as "Code Name: Lily" on DTM MAGAZINE, published in May 2010. The voice source is the lead vocalist of m.o.v.e., Yuri Masuda, whose given name literally means 'lily'. The idea of developing a VOCALOID based on Yuri's voice occurred, as one of the members was a user of VOCALOID. The illustration of Lily's VOCALOID was used on the Anim.o.v.e album while the voicebank was in development.
Additional software V3 Lily was announced in early 2012 for
Vocaloid 3. One of the earliest notes about this was that the new V3 Lily vocal would have a slightly larger vocal range. In July 2013, Internet Co., Ltd. announced a Mac update of this product for the
Vocaloid Neo engine. Two vocals were included with the package
V3 Lily; Native which is an update of the Vocaloid 2 vocal and
V3 Lily, which was a newly recorded voice. When imported into
Vocaloid 4, the vocals will be able to cross-synthesize with each other. Lily and
Gackpoid were brought up in a tweet during the
Megpoid English development. But English vocals could only occur if they were profitable. In October 2014, it was noted they currently have no plans for a Lily English.: ==Characteristics==
