Pah, Kasumi, no contest. Her three sisters not only look completely alike physically (other than their hair and clothing colors), but they're valley girls; a personality of urban-legend status but incredibly grating on my nerves nonetheless. Kasumi is INCREDIBLY fortunate that she didn't turn out like them. It must have something to do with the age difference between her and her sisters (who I have always assumed to be triplets for some reason o_o; )
