Originally Odin's bodyguard. After the battle with Loki and Fenrir, Odin leaves her in Issei's town. She then gets persuaded by Rias to become her servant. She remains in Kuou Academy as a teacher.
Rossweisse is known to be a very serious person, acting professional prioritizing work and study above all else since her youth, this however, caused her to miss out on romance, thus is extremely bitter and sensitive about not having a boyfriend and is quick to anger or sadness when made fun of. She has taken a liking to her role as a teacher in education for her students, making sure they understand her lessons and helping them whenever they're in a bind and is appreciated for it. Rossweisse has little tolerance for those who behave unprofessionally, especially for lewd acts at inappropriate times. When she lectures them on standards, they usually retort with her simply being jealous. This may have some truth to it as on numerous occasions she has expressed interests in doing perverted things with her future boyfriend, she also desires her lover to be financially stable with a bright future.
Despite her seriousness, she is stated to be clumsy and has a tendency to make rash decisions without informing anyone. She is highly susceptible to alcohol as one drink from it can leave her drunk and vomit for extended periods of time. Rossweisse has a lot of repressed baggage from upholding her uptight and modest demeanor which goes out the window when drunk and begins opening her true thoughts and frustrations. She also has a compulsion to buy things at sales when they're cheap, showing enthusiastic excitement whenever she goes to 100-Yen shops, causing Issei to dub her "The 100-Yen Shop Valkyrie". Rossweisse also has a tendency to speak using her country's accent when she is flustered.
Like the other girls, Rossweisse acts like someone her age whenever she is on a date with Issei as she ended up acting shy when she was called cute. She soon develops romantic feelings for Issei in Volume 17 when he proclaimed to her that he will protect her from Euclid, which he did.
After falling in love with Issei and becoming engaged to him, Rossweisse has started to partake in perverted activities she normally frowns upon, such as wanting him to apply suntan oil on her, sleeping with him while wearing revealing lingerie and fighting with the other girls over him.
Powers & Abilities
As a Devil, Rossweisse has the power common to a Devil, which allows her to cast spells and special phenomena. However, instead of using demonic powers to cause different phenomena, she prefers to use calucations rather than using her imagination.
As Odin's former bodyguard, Rossweisse has considerable magic power enough to be recognized for her position. In Vol 11, Azazel noted her powers equals that of a High-Class Devil despite her not being a Bishop. In Vol 25, even the Strongest Valkyrie, Brynhildr has recognized that even without Mistilteinn, her magic power already surpassed hers.
As a Valkyrie, she has higher physical abilities than a normal person, which was raised after being reincarnated into a Rook.
Rossweisse has enhanced defenses befitting her status as a Rook.
Rossweisse is a genius in Norse Magic, despite lacking talent in her house's Seiz-Style Spirit Magic, she realized she was talented in others, such as Rune-style, Gondol-style, offensive magic, and those not used in their house, exceeding Rias and Akeno. She could teach others as she taught Asia about basic summoning magic, and other kinds. Rossweisse uses a high-level, intricate and self-invented magic circle, strengthening her spell's offense and defense, while restraining magic power to the bare minimum. Le Fay and Euclid complimented her talent, letting her theorize a spell that could seal Trihexa, the latter stating it wasn't inferior to her grandmother, a famous Norse magician. She can strengthen her further magic using Mistilteinn, which allowed her to overpower Brynhildr and Akeno.
- Elemental Magic: She notably excels in the use of ice, fire, water, lightning, wind, thunder, light, and explosive-based magic. It is noted that she has inherent talent at studying and learning offensive magic. Rossweisse has demonstrated great offensive power with this magic, as she was able to finish off several Midgardsormr clones after they were weakened and knock down Sairaorg Bael after he let his guard down, despite him being enveloped in Touki.
- Defensive Magic: Upon returning from her training in Valhalla in Vol 12, Rossweisse starts to use defensive spells (using the trait of Rook), which are strong enough to easily shield against Balance Breakers that specialize in destructive power. She also learned defense magic to negate the adverse effect of touching holy objects such as Holy Swords and the Holy Bible for a short period of time. As seen when she used two of Xenovia's Excalibur fragments (Transparency and Mimic) by putting multiple layers of defense magic on her hand during the Rias-Sairaorg Rating Game match and reading a Bible without suffering a severe headache.
- Sealing Magic: Rossweisse can also use sealing magic, which she learned by researching the information about Trihexa. Used in conjecture with barrier magic, she can seal the movements of mass-produced Evil Dragons in Vol 19 by studying Asia's Evil Dragons. After modifying her technique, her sealing barrier technique was used by Three Factions to seal the Emperor Beast of Apocalypse. She could also use it in combat to seal her foes. Her barrier was even effective against Armaros, the Grigori anti-magic specialist although she needed time to prepare a stronger barrier as his anti-magic abilities could destroy a half-baked barrier. In Vol 25, Rossweisse, by enhancing her power with Mistilteinn, could use her Barrier magic to seal off entire areas to prevent her foes from escaping.
- Teleportation Magic: Rossweisse is proficient in teleportation magic.
- Summoning Magic: While she does not excel at it, Rossweisse possesses knowledge in summoning magic as she was capable of teaching Asia the basics of summoning magic.
- Enhancement Magic: In Vol 22, Rossweisse can use this magic to enhanced her own physical abilities, such as increasing her speed. In Vol 23, she could enhance the physical abilities of the entire Team Red Dragon Emperor of the Blazing Truth team.
- Hypnosis Magic: In True Vol 1, Rossweisse can use hypnotism magic on Ingvild Leviathan to lose consciousness.
- Security System Magic: Rossweisse has some level of skill with Security System magic, as she tried to use it to undo the technique placed on Issei.
- Black Magic
- White Magic
-Clothing Manipulation: Rossweisse is capable of using magic to altering her attire, changing from her formal suit into her Valkyrie armor.
Before she was reincarnated, Rossweisse could fly via magic like Loki could. After being reincarnated as a Devil, Rossweisse can now fly using her devil wings.
Equipment
This is an old looking, but powerful wand, which has powerful magic inside it, meant for god-class beings from the Norse World. Despite not mastering it yet, Rossweisse could use it to further strengthen her already powerful magic; increasing her defensive magic able to deflect Brynhildr's magic sword and her magic bombardment, which retired the Chief-Valkyrie in a single attack.
Rossweisse was reincarnated using the Rook Piece, which grants her enhanced offense and defense. Although, she used its defensive traits to strengthen the effectiveness of her defensive barriers.
