"Oh, hello there, I'm Hjörprimul, one of Valkyries who will fight by your side, I will devote myself to the Einherjar I swore loyalty to, as long as you tidy up, along with your manner."

Hjörprimul is Ror Valkyrie fan roster and Chevalier d'Éon's partner.

Hjör wears Musketeer-inspired Valkyrie uniform with white headdress that covered her tied blue hair, beneath her green musketeer coat and ruff collar, she wears dim blue blouse and white trousers with blue and yellow kokoshnik pattern, paired with high-heeled boots.

Hjör is very feminine despite wearing rather masculine attire based on 17th century musketeer blended with French duelist, at the same time wearing headdress with ribbon similar to 18th French female commoner but as fierce as her Valkyrie sisters, very close to her sword twin sister Skalmöld, Rangriz, Gondul and Herja.

Hjör usually speaking in soft-spoken tone, nurturing and motherly. She occasionally working as housemaid when off Valkyrie duty. Sometimes she stayed with her sisters in Valhalla or staying in Maison d'Éon in Tonnerre, France. She is good friends with Margo, the eldest d'Éon and Margo's husband Thomas O'Gourman.

Hjörprimul means 'Sword-Warrioress', which fitting for her Einherjar partner d'Éon who bears the title 'La Pucelle de Tonnerre' as Hjörprimul will transform into schiavona sword during völundr, both for slashing and thrusting. She specialized in European swordsmanship including fencing and hema.
