High School DxD, Vol. 13 (light novel) — Ichiei Ishibumi

For teenage-pervert-turned-demon Issei Hyoudou, every day is a battle. He might star in an underworld movie on one then get recruited to save a cute monster trainer girl from an arranged marriage the next. Even when he's sick, the excitement never slows down (thanks to some lovely ladies in nurse costumes). This second collection of short stories highlights some of Issei's and the Occult Research Club's wild adventures!
