Carmen

Carmen (カルメン, Karumen) was a rival cook of Zeff's, and eventually of Sanji's as well. She challenged Sanji to participate against her in a cooking contest. Sanji, at first, wasn't interested in the challenge as he was more interested in her. But a humongous fish called the Blue Fin Elephant Tuna was offered as the first prize, and Sanji was convinced to enter. It came down to him and Carmen in the end and before the victor was announced, Carmen conceded defeat, knowing she had lost, but bore no grudge against Sanji. She is followed around by her two short assistants, Leo and Jose. She is described as a big liar by both of her assistants.
