Kris Athena Black is the only daughter of the mass murderer, Sirius Black. When he was sent to Azkaban, Kris went to live with Lupin since the Potter's were dead and Harry's living situations weren't exactly the best. Kris's mom was killed by Voldemort, and Kris was only two months old. Kris was born a Metamorphmagus and at the age of 6, she was able to master a skill that only third years at Hogwarts were taught. She could become an Animagus. Dumbledore gave Remus Lupin, who became her care taker after Sirius got sent to Azkaban, special permission to train her in Transfiguration lessons throughout her life. According to Dumbledore, she could amount to something great by being a spy for the Order. When she is accepted to Hogwarts, she becomes well aware that she might become friends with Harry Potter. As she arrives in Diagon Ally with Lupin, she notices her uncle giving someone suspicious looks. She later discovers that it's Lucius Malfoy, and ex-death eater. When she notices her uncle scoping out Malfoy, she also notices that Draco, whose name she didn't know at the time, starring in her direction. She kept noticing him and his observance of her, as well as him noticing there's something off about Kris, but he didn't know what. (Draco X OC love story, don't get offended)
