what 日本动漫 is this from?

My guess? Pandora Hearts. My research suggests the character is Abyss, who is often accompanied 由 a stuffed-looking rabbit, and it's a pretty 流行的 show, making it rather likely.

If it's not, I can continue the hunt. Just let me know. = )

She could be from Haiyore! Nyaruko-san.
