Kouki Hyoudou always knew he was different. Born with an unusual power he calls Infinite Arsenal, Kouki can create or replicate any ability he desires—though he’s never dared to test its limits. Living alone after his parents left for an overseas business trip, Kouki tries to keep his life simple, balancing school, anime nights, and his quiet days in Kuoh Town. But things take a turn when he accidentally summons Rias Gremory, a powerful devil and Kuoh Academy's idol. What starts as a simple wish to share anime with someone becomes the start of a strange and exciting friendship, leading Rias to become his housemate and partner in chaos.
