What anime is this picture from?

[Caleb]

I came across this picture and couldn't identify it, does anyone know what anime it's from or is it just some deviant art drawing?

google told me that it is "vocaloid gas mask"

so probably not from an anime

This picture happens to be fan art, but it seems like the picture represents Gumi Megpoid from Megpoid, (Vocaloid).

This is what she looks like.

In case you didn't know, Megpoid is a singing Synthesizer program.
