Astrid is a typical high school girl who often arrives late in class, doze off to sleep during maths, and cry her brain cells to go home and just stay inside the four corners of her house, until one day a boy with mysterious, cold, and beautiful green eyes arrives and started to change things in her life that she never thought would even happen to her, and finds out she's not just any other teenage girl who fights her days to wake up early and answer math equations, but a kind of girl with magical abilities she never would thought to exist in the 21st century. She's a Champion! Together, with her new formed group of friends, they will go on a journey in defending their own kind, and protect themselves from the threat coming to them by their enemy, the Enchantress.
