Katana Maidens ~ Tomoshibi.

Our world is under constant threat from supernatural creatures called Aradama. Only the Toji, priestesses of the sword, can repel them. To do so, they join a special police brigade. The government has created five schools that train future priestesses. These girls are already putting their knowledge into practice to protect the population, but what drives them is the great tournament planned for next spring that will designate the best among them.
