Sasami: Mahou Shoujo Club

Sasami Iwakura was born with magical powers, yet a promise to her parents has kept her from using them openly. At the start of a new school term, she befriends the lonely Misao and is drawn into teacher Washu's seemingly ordinary cooking club, only to discover that it is secretly a place for girls like them to understand and control their magic.

Sasami soon meets other young witches with abilities they have spent years hiding. As the girls train, travel to the world of magic, and grow closer to one another, their harmless club activities begin to place them near a larger conflict over how magical people should live alongside ordinary humans.
