High School DxD, Vol. 3 (light novel): Excalibur of the Moonlit Schoolyard

With a sports festival on the horizon, the Occult Research Club expects smooth sailing after all the recent trouble. Everyone seems happy enough-except for Kiba, that is. The pretty boy hasn’t been himself since he saw an old picture of Issei. Things only get worse when two beauties arrive in town with powerful Holy Swords called Excaliburs-deadly weapons Kiba long ago swore to destroy. Issei promises to help his friend, but do the demons really stand a chance against such legendary might?
