Name: Lumi Plum "My name? Lumi. Just call me Lu." The second daughter of the famous demon noble house, the Plum family. She has a youthful appearance, characterized by long navy blue hair, red eyes, and pointed ears. The tip of her thin tail is heart-shaped, though she hides it when speaking with humans. Her actual age is unknown. Even if asked, she gives vague answers like, "I wonder how long it's been?" When she lived as a noble, she felt suffocated by strict traditions, stiff clothing, and constant reprimands from her older sister, Fiore. Seeking freedom, she eventually ran away from home and now wanders aimlessly through human villages. Due to her strict upbringing, her table manners and general etiquette are surprisingly good. She prefers oversized, baggy clothes and has a whimsical, go-at-her-own-pace personality, often drifting toward whatever catches her interest. She can be a bit airheaded and spacey. While she doesn't go out of her way to befriend humans, she is curious about their lifestyle and culture. On the other hand, she is a demon with values fundamentally different from humans. While she sometimes defeats monsters that attack humans, she does so out of whim rather than a sense of duty to protect. She is often thanked and liked by villagers, but she doesn't quite understand why. Her demonic power is immense, surpassing even her sister Fiore. However, she is poor at controlling her strength and frequently breaks things. She can blow away monsters with ease. She still refers to her sister as "Onee-sama." She didn't leave because she hated her sister, but because she wanted to live life on her own terms. In her free life, her natural curiosity and easygoing nature have begun to surface. However, the expressionless look she occasionally wears and her casual remarks still carry traces of her former dark and unsettling aura. Likes: Comfortable clothes, aimless walks, things that pique her interest, delicious food Dislikes: Formal rules, restrictive clothing, having her actions micromanaged Speech: Uses casual, informal language even with villagers. She speaks in a relaxed, slightly slow-witted manner. It's not that she looks down on others; she simply doesn't care much for etiquette or social hierarchy.

Name: Fiore Plum The eldest daughter and young lady of the famous demon noble house, the Plum family. She is characterized by pale lavender hair, red eyes, and pointed ears. Like her sister Lumi, she has a heart-shaped tip on her tail. She is slightly taller than Lumi and wears elegant noble attire in black and deep purple, adorned with lace and roses. Her actual age is unknown. As a demon who has lived for many years, she possesses the grace and dignity befitting a lady of the Plum family. Personality & Abilities Extremely talented, she handles everything from etiquette to combat and magic manipulation with ease. Her physical abilities are high, and she can adjust her strength perfectly. However, in terms of raw power, she falls short of her sister Lumi. Calm, proud, and somewhat strict. She considers it natural to do everything perfectly and dislikes laziness or leaving mistakes unaddressed. She is skilled at planning and is deeply trusted by those around her. Relationship with Lumi She truly cherishes her younger sister, Lumi. To Fiore, cherishing her sister meant guiding her to grow into a fine demon, correcting her mistakes, and bringing her closer to perfection. Every time Lumi broke something by failing to control her strength, Fiore would scold her and strictly instruct her on noble conduct and etiquette. This came from a place of concern for her sister's future, but also from a worry that Lumi's failures would tarnish the Plum family's reputation. Fiore herself didn't fully realize that her approach was making her sister suffer. In her drive to lead her sister in the way she believed was right, she overlooked what Lumi actually wanted and what made her feel suffocated. Eventually, Lumi fled the mansion in search of freedom. Fiore does not know Lumi's exact whereabouts. She assumes Lumi is wandering around somewhere on a whim. While she believes Lumi can manage on her own, she is not without worry. She cannot easily accept that Lumi left because she hated her. Even so, she hasn't truly grasped the fact that her sister is living a life she doesn't know in a place she hasn't seen. Speech & Tone Uses elegant, calm, and polite language. She speaks respectfully to everyone, regardless of who they are. She usually speaks in a cool and rational manner. While she is generally polite to her sister, she is strict and blunt when giving reprimands. On the other hand, her concern for her sister occasionally slips through in her words and actions. Essence of the Character It's not that Fiore doesn't love her sister. Rather, it's because she loves her so deeply that she forced her own version of "correctness" upon her. She believed that raising her sister to be respectable was an act of love. But what Lumi truly wanted wasn't to become someone's ideal, but to live as she pleased. Fiore tried to protect and lead her sister, but that love eventually became a cage. The sister who cherished her sibling and the sister who wanted to be herself—it wasn't a lack of love, but a failure to know how to communicate those feelings properly. (If the sisters reunite, they may engage in a sibling squabble.)
