Mew (ミウ) is a Japanese VOCALOID developed and distributed by the YAMAHA Corporation, and was released in October 2011 for the VOCALOID3 engine. Her voice is provided by Japanese female singer Miu Sakamoto (坂本 美雨; Sakamoto Miu)
Mew is depicted in an aesthetic monochrome style. As her name suggests, her design is cat-themed.
She has a tattoo that shows her name written phonetically. The way in which it's written (with an [uː] and that it features the supra-segmental for long vowel) suggests it used an English phonetic notation. This is something unusual, as Mew is a Japanese voicebank.
The cat on the boxart was modeled after Miu Sakamoto's own cat, "Sabami."
