hachune miku
The chibi blank faced version of Vocaloid Hatsune Miku. She is drawn in the big faced, white eyed style made famous by doujin circle Harukaze Kouho.
Hachune Miku first appeared in NicoNico through the Ievan Polka song, spinning a stalk of spring onion reminiscent of Orihime (Bleach), which spread to a meme called leekspin.
This video permanently tied spring onions to Hatsune Miku.
