Moroha enters Akane Academy, where he and his classmates have each inherited mystical powers from their former lives. There he meets Satsuki and Shizuno, two girls who immediately find themselves drawn to him for various reasons.

Moroha and Shizuno are invited to join the renowned Strikers, leaving Satsuki out in the cold. But when a powerful Metaphysical attacks a crowded shopping district, the trio find themselves fighting it all by themselves.
