Magical Girl Battlefield

Eleven of the world's best magical girls have been chosen to play a game. The rules are simple, defeat the monsters and collect their shards. The selected few who have the most win. But there's a catch. This is also a survival game.

Miyu Ashia, a 16 year old from Tokyo, Japan, is one of these girls. When she's suddenly thrown into this game she has to use all her power, as there's a possibility she won't make it out alive.

Inspired by Madoka Magica (but I also have my own original ideas)
