After Akira Kurusu, formerly Harry Potter, accepted his new name and created a bond with his parents, he wasn't the only one, who accepted the change. Lady Magic herself did agree with the change. The name Harry Potter disappeared from all magical records in the wizarding world like a Harry Potter had never existed and Lady Magic cut the ties between Harry Potter and his biological parents and two of his godparents and replaced them with the Kurusus, and this was going to be painful for James, Lily, Sirius and Remus, because if Lady Magic cut the ties between the child and the godparents/parents, then the godparents/parents were the ones, who were going to feel the pain. In addition, the twin bond with Akira's biological twin brother John Potter was severed and this would be even more painful, because Lady Magic had seen the twin bond as a leech, where John was getting the magic from his twin brother without repaying it back, in order to balance it out with his twin. It seemed like that John Potter was only powerful, because he was getting the magic with the help of the twin bond from his twin and never had bothered to create his own magic, but without it, the power level of the boy would fall to mediocrity. And from that day on a Harry Potter ceased to exist in this world, but an Akira Kurusu was born, who was going to piss off a certain manipulative headmaster.
