Magical Girl Raising Project, Vol. 13 (Light Novel) Black Volume 13

"With only fifteen students in total, and all girls at that, Umemizaki Junior High's class 2-F is a bit peculiar. In fact, "peculiar" doesn't even cut it--this is a special class that the Magical Kingdom created to raise the next generation of legitimate magical girls! From the outside, these elite students represent a beacon of hope for the future. But behind closed doors, something terrible is brewing."--Publisher's description.
