is introduced as the princess of Tristain; her element is water magic. She is loved by her nationals and is a childhood friend of Louise. She defends Tristain from the Albion invasion after the assassination of her lover, Prince Wales. Her role is developed more in season two, where she is crowned queen (although Louise and her friends still refer to her as Princess), and must deal with an impending war against Albion. In the manga, Louise succeed in delivering Wales' letter; however, Henrietta renounces her marriage unable to ignore the crisis in Tristain.

Henrietta seems to be friendly with Saito, even though she was unintentionally kissed by Saito on the lips in the first season. She envies Louise for her bravery. In Season 2, Henrietta has Saito be her bodyguard to counteract a spy, but they find themselves in some heavy but feigned romantic situations: when she is walking with Saito on the street and pretends to be his lover, she puts his hand on her chest; when the guards barge into the inn room where she and Saito are hiding, she passionately makes out with him. In Season 3, Henrietta starts showing romantic feelings to the point where Louise considers her a love rival. At the Slepnir Ball, Henrietta disguises herself as Louise, receiving a hug and a kiss from Saito. When asked to intrude Gallia to recover Tabitha, Henrietta refuses, and in the process, holds Saito's hands, which shocks Louise, Saito and even Henrietta herself when she realizes it. She tells Louise she does not know whether she is rebounding from Wales or if she is truly falling for him. In Season 4, Henrietta grants Saito ownership of De Ornielle (a derelict mansion since there was no successor for it previously) after his deeds in saving Romalia. Beneath De Ornielle, Saito discovers a secret room where Henrietta's paternal family used to rendezvous with their genuine mistresses, most likely because of forced engagements. She admits she has feelings for Saito. They kissed each other, and Louise discovered them. Louise is not happy about this, and they had a brief fight over it. Ultimately, Louise accepts her feelings for Saito, but slaps Henrietta for "using her familiar."

Henrietta's feelings for Saito are made more apparent in the light novels. Saito was initially determined to not go further with Henrietta, but Henrietta just wanted to "spend a few moments of happiness" with him. Henrietta is named after Princess Henriette Anne Stuart of England from 1644 to 1670, a Princess of England and Scotland, cousin of Louis XIV and wife of his brother, Philippe of France.
