She is a mascot of a certain vocaloid. That's why tag "vocaloid" is there.

To let you know, no bad comments because the tags were mixed. There isn't a mouth for a mouth tag, neither a nose.

Sry for the inconvenience.

What site did you get it from? Because it looks like Miriam fan depiction art.

I got it from the official vocaloid wiki.

okay, found it
it is meant to be a variant of Miriam.

Kthx.
