How Many Episodes: 12
Synopsis: Issei Hyoudo is admittedly a pervert who isn’t ashamed of peeping on girls and dreaming of ultimately having his own harem. His dream begins to turn into a reality (though not in the way he’d imagined) when he’s asked out on a date by a beautiful girl who turns out to be a fallen angel! What’s worse, he’s brutally killed by her, suddenly revived by bare naked devil Rias Gremory who he awakens to, and has now become a devil himself! As her new servant, he joins the school’s Occult Research club, learning that his entire student body is flooded with beautiful angels, fallen angels, and devils among humans like him. It’s a dream come true. Almost.
