She has blue eyes and had long blonde hair that reached her legs.She was often seen in a female middle school uniform.
She is named by Liana, one of the people who discovered her sleeping like a princess in a coffin next to Kojou, Nagisa and Gajou. The name is taken from the sleeping beauty. Avrora was responsible for guarding "Root" residing within her. She was sealed in an old ruin known as Fairy's Coffin. Shortly after Nagisa conversed with the old ruin, they were attacked by the Faction of Emperor of the Black Death. Kojou used his body to protect Nagisa and Avrora from the hail of bullets aimed at them. Kojou was on the verge of death as his chest was in pieces. Avrora, admiring his courage, donated her fourth and fifth ribs, turning Kojou into her blood servant and defending the terrorist attack. Approximately three and a half years later, "Root" found himself desperate as the fourth birthright in Nagisa's body and hunted the other Kaleid Bloods to consume them. Avrora and Kojou managed to gain loyalty from the other Kaleid Bloods and Kojou helped defeat a "root". Avrora absorbed "Root" from Nagisa and declared that "Root" must be destroyed. Avrora considered that Kojou deserved to be the successor of Kaleid Sangre / the fourth elder, ordered Kojou, her servant of blood that is destroyed along with "Root". Nagisa managed to transfer Avrora's consciousness inside her just before she perished. Her body is preserved in the MAR research lab as part of the "Sleeping Princess" project.
