At Koryo Academy, students battle with weapons forged from their souls. Kokonoe Tor, however, is an Irregular. He doesn’t have a weapon – he has a shield! To gain the strength he seeks – and thus, unravel the truth of his tragic past – he must form a Duo with another student. But first, he has to figure out how to share a room with a girl, the graceful fighter Julie Sigtuna, and not die of total awkwardness.
