Keigo

They sent her to a facility that practices giving people quirks and accidently turned her into a hybrid. Another accident erased her memory of ever being fully human and her parents turned her away when she was titled a failed experiment. The scientists had no choice but to send her to a pet store where she would most likely be euthanized.
