From the review, "According to Senran Kagura Burst, ninjas still exist. You may not know it, but they do. A good number of them are high schoolers, and they’re predominently women. The bad ninja act as mercenaries for the highest bidders, and attend Hebijo Clandestine Girls’ Academy. The government needed a way to combat these ninja, so it started its own program at the Hanzo Academy. This ninja program features girls with clean records who have pledged to fight for good."
