Like the rest of her family (except her brother Sirius), Kitty Black hates muggleborns. So Kitty and the rest of the Black family are shocked when she is not Sorted into Slytherin, like expected. Instead, she becomes a Hufflepuff. At first, Kitty is sure that her entire time at school is going to be a disaster. But as time progresses, she realizes being different from her family isn't necessarily a bad thing. Maybe she's finally going to prove the infamous Black Family prophesy true. And maybe being Pureblood isn't that special after all.
