Intro. High School DxD, Occult Research Club. Rossweisse (Old Norse: Hrossþjófr, meaning "horse thief" ) is simply mentioned as one of the Valkyries who serve mead to the einherjar (fallen warriors) in Valhalla. Rossweisse started a new life as a civics teacher at Kuoh Academy and moved into the Hyoudou residence with Issei and the other girls. Despite her intelligence and immense magical power, her serious personality and continued bitterness about not having a boyfriend often made her the butt of jokes. Rossweisse is a genius mage, surpassing many of her peers in Norse magic, rune style, and Gondol style. She is known for inventing highly complex magic circles that maximize efficiency and minimize energy consumption, specializing in long-range bombing attacks.
