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 few people who discovered her sleeping like a princess in a coffin alongside Kojou, Nagisa and Gajou. The name is taken from The Sleeping Beauty. Avrora was responsible for guarding "Root" that resides within her. She was sealed at an ancient ruin known as Fairy's Coffin. Shortly after Nagisa conversing with the ancient ruin, they were attacked by the Black Death Emperor Faction. Kojou used his body to protect Nagisa and Avrora from the incoming rain of bullets towards them. Kojou was on the verge of death with his chest blown away into pieces. Avrora, admiring his courage, donated her fourth and fifth ribs turning Kojou into her blood servant and fended off the terrorist attack. Roughly about three and half a year later, "Root" had awakened as the fourth primogenitor in Nagisa's body and hunted the other Kaleid Bloods to consume them. Avrora and Kojou managed to gain allegiance from the other Kaleid Bloods and helped them defeat "Root". Avrora absorbed "Root" from Nagisa and stated that "Root" must be destroyed. Avrora deemed Kojou's worthy of being Kaleid Blood's successor / the fourth primogenitor, ordered Kojou, her blood servant to destroy her along with "Root". Nagisa managed to transfer Avrora's consciousness inside herself just before she perishes. Her body is being preserved at MAR research lab as a part of the "Sleeping Princess" project.
