jahi tries to have a mermaid teach her to lure human sailors to drown to their death with a Siren Song. Doux succeeds in enchanting sailors, but only harmlessly causes them to watch her and cheer... and her song even works on the mermaid!She's always drawn with a single tiny fang on her mouth, which adds to her adorable appearance.She's a tiny demon girl who's constantly portrayed as adorable, even In-Universe. Ahriman greatly adores his daughter, and Doux loves him in return. A demon she may be, especially the next in line to rule demon kind, but is good-natured and innocent, that she can spreads this trope to the other demons. The trope is still in play as she turns out to be the good half of a dragon of destruction, but can also bring out the goodness of her own evil half whom she regarded as her mother, showing that even one made of evil can turn good by her presence.She is not actually Ahriman's daughter in a normal sense. She's rather the result of his splitting an ancient dragon's good and evil halves apart, with the evil side being her "mother" Dahaka. Doux however regards both as her parents and adores them both - in fact her calling them "Mama" and "Papa" is what prompted them to keep her. However, the spell Ahriman used to separate Dahaka had a visible impact Doux's formation, causing her to "inherit" a combination of physical and magical characteristics from them both. This made Doux effectively their "biological" daughter as well as an adopted one. Jahi's efforts to teach her magic to torment the slaves fail at first, as Doux mostly uses it just for minor cantrips, but then she shows immense potential with ice magic. Of course, Jahi is deflated when Doux uses it to treat the slaves instead.Due to being such a good-natured demon, Ahriman is worried about how her reign as the next ruler of the demon realm will go and tasks Jahi to put Doux through various trials in order to awaken her wicked nature... to varying results. Doux is an innocent demon who has nary a malicious bone in her body. Her goodness is so infectious that it starts affecting everyone around her, to the point Jahi considers she might "destroy evil itself". Doux and her Mother Dahaka were once a powerful dragon, whose powers Ahriman wanted. Using an artifact, he split the dragon's good and evil sides. Dahaka is the evil side, Doux is the good side. Be it demons, humans, angels, or wild animals, almost any creature alive ends up loving Doux after interacting with her for a few moments. She is the physical embodiment of Dahaka's goodness separated into a new being. This makes her benevolent on a level so fundamental that it brings out the best in everyone she interacts with. "Doux" means "gentle" in French, and she's as sweet as can be. Her father wanted her to be the inheritor of his evil empire, but is mortified that she nothing but kind. Ahriman tasks Jahi with training her in villainy, but Doux's innate kindness always results in the exact opposite result, much to Jahi's frustration. She becomes one to every demon or other evil being around her. Non-Human Humanoid Hybrid: She's the magically created hybrid of a demon lord and ancient dragon. Her demonic side seems to be dominant. despite being a tiny child, while she's physically weak, she still inherited her father's immense magical powers... which she mostly uses to help others. Demon heritage aside, she fits this to a tee. She’s the adorable daughter of a powerful king, and an incorruptibly pure friend to all creatures and people, with even a habit of breaking into song. Despite being spoiled rotten by her father and subjects, she somehow ended up as the kindest demon in all the realm. Doux inherited her father's magical powers, but she's about as physically strong and durable as a normal human little girl. Doux is genuinely kindhearted and wants to do good in contrast to the other demons' selfish desires. It's later subverted, she's not actually a demon, but the good half of an ancient Dragon. To Jahi's distress, Doux mostly uses her innate magic powers to heal others.
