Chrno crusade

A shoujo Manga and anime featuring nuns with guns. For the main characters it has a Headstrong, 16 year old nun called Rosette Christopher and a friendly Demon called Chrno who both work for the Magdalene order, an order devoted to slaying demons and demon summoners. It is like a baby version of hellsing, but still a decent piece of work. Spelled Chrno to avoid confusion with the games chrono trigger and chrono cross
