Story
Ridel Cross is simply the fourth daughter of an ordinary knight, or at least, she was until her 18th birthday when she awakened her barrier magic skills. When the emperor learned of her magic skills, he summoned her to work for him. Sadly, “work” in the emperor’s definition meant being locked up in a magic tower to be treated worse than a slave and used as a tool. One day, after 10 long years of misery, Ridel cries herself to sleep while rueing the day she revealed her barrier magic. She silently wishes that she could go back to her 18th birthday and change her life.
