Magical Girl Raising Project(2014)

Mahou Shoujo Ikusei Keikaku

Sugar and spice--but not playing nice! The manga based on the hit novel series! Magical girls like Snow White and La Pucelle have dreamed of the day they'd become one of the lucky few chosen to protect N City. But their dreams quickly turn into a nightmare when the Magical Girl Raising Project Management Office issues a decree--there are simply TOO MANY magical girls! Oops! Time to cull the number by...half? Half sounds good. Don't worry, retirement just means...you die. Good luck, girls!
