Smile of the Arsnotoria the Animation

The Pentagrams are students at Ashram, a magical academic city, where they study general education, magic, and etiquette to become proper ladies. Their school, hidden from the outside world, is home to several girls, like Arsnotoria, a Pentagram in the fifth dorm house, and her roommates Mell, Little Alberta, Picatrix, and Abramelin. As part of their duties, the Pentagrams must also exterminate bugs that are sensitive to magic, which can harm the city's magical flowers.
