Cinderella Nine × The Melancholy of Haruhi Suzumiya: Yuzu Takanashi, Yoshimi Iwaki and Haruhi Suzumiya doing the "akanbe" gesture

Notes:

Akanbe (あかんべえ, Akanbē) is a facial gesture often used in Japan to indicate sarcasm, but also as a taunt. It consists of pulling down one's lower eyelid to expose the palpebral conjunctiva towards someone, often accompanied by sticking one's tongue out.
