Warau Arsnotoria Sun!

Welcome to the magical city of Ashram, where a group of girls known as Pentagrams are studying to become proper ladies. They receive lessons in general education, magic, and etiquette, while being hidden away from the outside world.

One of the Pentagrams is Arsnotoria, a girl who never smiles. She lives in the fifth dorm house with her beloved roommates: Mell, Little Alberta, Picatrix, and Abramelin. Despite their different personalities, they spend as much time together as possible. When their duties are done for the day, they even sneak off to their secret room for a tea party.

But their peaceful lives are threatened by bugs that are sensitive to magic. As part of their education, the girls must exterminate these insects. Could there be more to Ashram and the Pentagrams than meets the eye?
