Ahriman's suggestions and the bizarre magical artifacts he gives her to help her tasks are often more of a hindrance than a boon, but since he's the Demon King, she can't just refuse his help.She wears a purple longcoat as her uniform in the Demon King's army. To Doux. While she fails at being The Corrupter, she does teach Doux alot about the world they live in and trains her in various areas. Whenever she gets angry or upset, her pupils fade away, and her eyes become completely blank. As the story progresses, her respect for her Demon King drops more and more, and she watches him act like a Bumbling Dad and realizes he's Powerful, but Incompetent. Buxom Beauty Standard: As Sati puts it, Jahi has "gigantic udders" that she thinks are wasted on her since she doesn't know how to use them. To prove her wrong, Jahi does try to seduce a prisoner by playing up her assets, and while it seems like it's working, she eventually gets too embarrassed by the man gawking at her cleavage and just starts pummeling the guy. Her frustration with Doux's kindness and her failed attempts to make her evil is the primary source of humor in the series. Cool Big Sis: Jahi is supposed to be teaching Doux into becoming a proper demon, but eventually, Jahi couldn't resist Doux's charm and started doting on her as well. A side story shows she has trouble buying clothes due to many feeling tight due to her large chest. Jahi is the Demon King's Number Two aide and is assigned several important tasks, such as leading his armies, administering his realm, or tutoring his goody-two-shoes daughter. She's a dignified Lady of War who wears a purple Badass Longcoat. She's assigned to teach Doux into becoming an evil demon like all others. She never comes close to succeeding. She's a demon general whose uniform has a high collar. She looks like a normal human woman, except for the single horn on the right side of her head. When she disguises herself as a human, hiding her horn with magic is the only thing she has to do. She's a great beauty with a voluptuous figure, but doesn't care much for her looks and thinks it's demeaning to rely on them. This is one of the reasons Sati dislikes her, since she'd kill to have the natural beauty that Jahi possesses and takes for granted. One of the few things she's awful at is cooking. Ahriman passes out after tasting one of her overcooked dishes, and even Doux can't pretend it tastes good. She's a feminine and graceful woman who often leads the armies of the demon king in his campaign. She has long blonde hair that she always wears down, which adds to her Lady of War appearance. She's a swordswoman who's adept in many types of attack magic. Her dragon form still retains her blonde hair and blue eyes, and her fur is purple to match the purple outfit she wears. Jahi has the build of a slim young woman, but she's one of the most dangerous demonic combatants around. She can hold off a dragon with physical strength alone and can create building-sized blasts of flame with one casual spell. She can use transformation magic to turn into a large, one-horned dragonic monster. Despite often berating Ahriman for spoiling Doux and thinking many of his plans are stupid, she also has a soft spot for Doux and tends to indulge in her wishes from time to time, and some of Jahi's Evil Plans to turn Doux evil can also get comically elaborate. She's constantly frustrated with the goofiness of her liege, the inability for her charge Doux to be a "proper" demon, and the lack of discipline in her colleagues. Jahi and Sati have a comical rivalry that dates back to when they were colleagues during demon training. After getting depressed over her repeated failures to teach Doux her intended lessons in their various trials, Jahi finally has a victory when she tells Doux that the purpose of transformation is to show strength and to "hide your weakness." Doux interprets this lesson by resisting crying in front of humans when she bruises her head in an accident, which Jahi proudly recognizes and praises her for. "Oh. Hi...I'm Jahi."
