Ursula is an astrology teacher at Luna Nova. Her real identity is Shiny Chariot, a famous witch performer and alumni of Luna Nova and the one who inspired Akko to become a witch. Her chosen mission was to use her magic skills to bring joy to people's hearts. She mysteriously disappeared from the public eye ten years ago after her former friend Croix tricked her into employing a sinister type of magic, which stripped Akko of her latent magical powers as a child. Now living and teaching incognito at Luna Nova, she takes Akko as a personal student after she notices her strong desire to become a witch, which enables her to use the Shiny Rod and unseal the lost seven words to the Grand Triskelion, in order to make up for her guilt.
