Huh... the first Hatsune Miku image uploaded to Danbooru. According to the stats she's the fastest growing character on the site and #11 overall. That's pretty impressive.

I still have to find a way to get me a copy of this...

the second upload... according to the upload order.

Truthfully speaking, due to

Any [direct] official works that have become memes (example: post #46660).

rule, we technically shouldn't have this in Origin pool.
At the same time, this specific art of Hatsune Miku started Vocaloid meme and memes involving herself. There are enough credible evidence that without that specific art by KEI, Hatsune Miku might have not made it, so...

my personal vote is to keep it in Origin pool. Anyone else is free to feel otherwise.
