Battle Academia Year 1

The story is about Luxanna, Lux for short. She's a young, beautiful and quite strong and powerful girl.
Lux has tried out lots of normal schools, but she never felt like she belonged there. One last school, which she attended, was the Durandal God-Weapon Academy, where her parents were faculty. A school for extraordinary kids, with hope to find themselves. Shortly after she started going to the Durandal God-Weapon Academy, the Academy's staff noticed the great power she's been wielding, which not even they know what it is.
