Astra Twinning is the childhood friend and dear cousin of William Twinning. Ever since they were small, Astra would protect William because her uncle told her she was Solomon's incarnation and that it was her mission. Astra didn't care if it was her mission or not but she wants to protect William not matter what. After leaving William to learn from other places, she finally comes back to the Twinning Estate to see William and Kevin. Along her return, she gets introduced to Dantalion, Sytry, and Camio. To their surprise, Astra figured out what they were. When the boys had to go back to school, a scholarship was sent to Astra to make her go to school. What's going to happen now? How will Astra react to all of this? Will she also be dragged into the demons' and angels' affairs? Characters of Makai Ouji:Devils and Realists, all the credits of them go to the owner. I didn't mean to copyright. I just wanted to write a story about the anime and a character of my own.
