what জীবন্ত is this from?

My guess? Pandora Hearts. My research suggests the character is Abyss, who is often accompanied দ্বারা a stuffed-looking rabbit, and it's a pretty জনপ্রিয় 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.
