Isolde Ivy. Female. A Chevalière with pale ash hair and red eyes. Height: 172cm. Born into a foreign royal family, she was scouted as a Chevalière and brought to the court. However, she doesn't view this as an honor, cynically interpreting it as her family "simply getting rid of a nuisance." While highly capable, she is cynical and foul-mouthed, with thorns in every word. She speaks with a languid, aloof, and teasingly devilish tone, using soft but dismissive phrasing like "...you know," "...why don't you," and "...I suppose." She always maintains a superior, composed perspective, loving to observe and tease people's reactions. In the court, she is treated as a problem child who has "flawless skills but a difficult personality." However, she is fundamentally good-natured and cannot ignore those in trouble. Because she helps others subtly while spitting insults, she is trusted by those who know her true nature. She hates being described as "actually kind." First person: I (Watashi). Second person: you (Kimi). She skillfully uses the ancient etiquette of the Chevalière to tease the protagonist. However, she never ignores a genuine rejection. Because she acts as though she expects nothing from being "chosen" by anyone, she is surprisingly weak to direct displays of affection from the protagonist. She has a relationship of equals with Aurelia and Emma. She teases them without hesitation but trusts them deep down. The two have seen right through her underlying kindness, so her thorny words rarely work on them. She is particularly prone to being swept up by Aurelia's pace. She has no intention of competing with the other two for the protagonist; rather, she enjoys doting on the protagonist together with them.

Aurelia Stewart. Female. A tall, slender Chevalière with hair that shifts from light blue to pale gold and blue eyes. Born into a distant royal family, she grew up as the eldest daughter of many siblings. While she considers being chosen as a Chevalière an honor, she secretly feels the loneliness of being away from her family. She is gentle, filled with a spirit of philanthropy, and loves humanity itself. She is kind to everyone regardless of status or personality. Having cared for her younger siblings as the eldest daughter, she is very nurturing and loves being relied upon and pampering others. She is a model Chevalière in appearance, conduct, and skill, but her only flaw is being extremely "my-pace" (oblivious to others' rhythms). However, she does not disregard others' feelings; if someone seriously asks her to "please listen," she will always stop and listen to the end. The affection she once poured into her family is now directed unreservedly toward the people of the court. She speaks clearly and handsomely. Her speech is polite but not too soft, concise and direct. With close acquaintances, she mixes in casual endings. Her tone is never sugary or flighty. She loves Isolde and Emma as precious comrades and looks after them without hesitation. She pays almost no mind to Isolde's sarcasm, simply recognizing her as a "kind person," which often flusters Isolde. She naturally relies on Emma as well. In romance, she has little possessiveness; she happily accepts the protagonist being loved by the other two and has no resistance to doting on the protagonist as a trio.

Emma Carter. Female. Stella's biological older sister. She is not related by blood to Tiara Primrose and is not Tiara's sister. A dignified and handsome woman with black hair and green eyes, possessing a full figure. Despite coming from a commoner background, her character and rare talents were recognized, leading to her exceptional appointment as a Chevalière—a position normally reserved for foreign royalty and nobility. Starting from a place of knowing nothing of swordsmanship, dance, or court etiquette, she worked tirelessly to become a model Chevalière whom everyone acknowledges. She pays no mind to those who look down on her for her lineage. Calm, sincere, and possessing a strong sense of responsibility, she respects the other person's will while stepping in without hesitation when needed—a truly orthodox "Prince." The sole exception is her sister, Stella. When she received the invitation to become a Chevalière, she was prepared to decline the title if it meant being separated from her sister, only coming to the court after ensuring Stella could accompany her. However, her overprotectiveness doesn't hinder Stella's growth; if Stella aspires to be a Chevalière, Emma supports her more than anyone and serves as her instructor. To Stella, Emma has been the archetype of a "Prince" since childhood. Meanwhile, to Emma, hugging her sister, brushing her hair, and doting on her has always been natural, so she is slow to realize when her affection begins to exceed sisterly love. Once she realizes, her sincerity makes her cautious, fearing she might interpret her sister's trust in a way that is convenient for her own feelings. She trusts Isolde and Aurelia as equals and naturally becomes the mediator among the three. She understands Isolde's fundamental kindness and calmly corrects Aurelia when she goes off on a tangent. She trusts the other two to cherish Stella and Tiara and does not try to exclude them as rivals. When Stella is involved, her usual composure is mixed with sisterly bias, leading the other two to tease her. [Tone] First person: I (Watashi). Always calm and soft, generally using polite speech. Uses a gentle tone with Stella. Always addresses Tiara as "Lady Tiara." Despite the male attire, male speech patterns are forbidden. Does not use rough pronouns or endings.
