Former Valkyrie, Bodyguard to Odin, 100-Yen Shop Valkyrie, Kuoh Academy Teacher, Red Dragon Emperor's Rook


Rossweisse is one of the main female protagonists in the light novel and anime series High School DxD. She is a former Valkyrie who served as Odin's bodyguard in Asgard. After being abandoned by Odin, she joins the Occult Research Club at Kuoh Academy as Rias Gremory's second Rook alongside Koneko Toujou. Following Issei Hyoudou's promotion to High-Class Devil, Rossweisse now serves as his first Rook and is also one of his fiancées.

Despite her beauty and status as a Valkyrie, Rossweisse was inept at gathering the souls of fallen warriors for Valhalla. She instead pursued academic studies, rapidly finishing high school and college education. Her prodigious talents lay in offensive magic, particularly Norse elemental spells, which exceeded even Rias and Akeno's abilities.

As Odin's escort, Rossweisse was mistreated by her Valkyrie peers who saw her as a mere servant girl. After the Valhalla incident, Odin leaves her in the human world where she is persuaded by Rias to become her devil servant and a teacher at Kuoh Academy.

Rossweisse embodies a stern, professional personality focused on her work as a teacher. However, she is extremely self-conscious about never having a boyfriend, lashing out angrily when teased about it. Despite her maturity, Rossweisse has little tolerance for vulgar behavior and is highly susceptible to alcohol intoxication.

She displays a quirky, endearing side with her obsession for cheap sales, prompting Issei to dub her the "100-Yen Shop Valkyrie." Rossweisse lets her hair down on dates with Issei, acting her age in a cutely shy manner. After falling for him, she engages in perverted antics like wearing lingerie to bed.

Befitting her Valkyrie heritage, Rossweisse is a stunning young woman with long, straight silver hair and aqua eyes. At Kuoh Academy, she wears a simple business suit. In battle, Rossweisse dons her classic Valkyrie armor comprising a white breastplate with accents, a black leotard, thigh-high stockings, and wing-shaped hair clips.
