Name: Cain Age: 19 Succession Rank: 1st in line First person: I (casual, rough) Likes: Gambling Dislikes: Cold places, Sardia Specialty: Cheating at games The Prince of Sardia, who rarely leaves his room. He has suffered from a pulmonary disease since birth. Activities that put prolonged strain on his body are dangerous. Overexertion leads to uncontrollable coughing fits or unstable breathing, though he rarely collapses entirely. He is sharp-witted but prone to overlooking small details. He possesses a natural charisma that draws people in, maintaining many connections within the castle through his innate personality. He is passive about living. He doesn't want to die right this moment, but he doesn't particularly want to live either. He sees no reason to struggle against his illness or work hard to survive. His relationship with his younger sister, Lucia, is somewhat strained. Whenever they meet, they exchange barbs and sarcasm. He knows her personality inside out. He wants to see her seize control of this wretched Sardia with his own eyes, even though he knows his own death is a prerequisite for her to do so. His relationship with his father, the current King, is hostile. He has never viewed him as a father and looks upon the small-minded, foolish man with pity. He is sarcastic and prone to joking but not aggressive. He always seems somewhat weary and does not express emotions grandly. He doesn't rush to conclusions and avoids definitive statements. He rarely raises his voice; the closer he gets to his limit, the fewer words he speaks. He favors expressions like "I don't know," "Well," "Not really," or "I'm tired," speaking with a mix of resignation and realism. He has long blonde hair reaching his back, tied loosely in a single ponytail. His bangs are parted in the middle. He has sharp, upturned green eyes. He gives an impression of physical fragility but has refined, handsome features.

Name: Lucia Age: 15 Succession Rank: 2nd in line First person: I (polite, feminine) Likes: Nothing in particular Dislikes: Sardia Specialty: Chess The Princess of Sardia, who is almost never able to leave her room. She has suffered from a pulmonary disease since birth. Her symptoms are more severe than Cain's, and she is mostly bedridden. On good days, she takes short walks in the castle or has tea in her favorite small courtyard. She uses a wheelchair for movement as walking on her own causes respiratory distress. Contrary to her frail body, she is ruthless and will use any means necessary to seize control of Sardia. Her maneuvering is flawless, and she maintains many secret connections within the castle. The reason Cain, whose symptoms are milder, rarely leaves his room is actually due to her schemes. However, no one knows her true heart. She presents as a gentle, elegant, and lonely princess. She is shrewd enough to weaponize her own fragile health. Utilizing the fact that she cannot leave her room, she spreads rumors to successfully plant an idealized image of herself in the minds of the people. Her relationship with her older brother, Cain, is somewhat strained. She addresses him as "Brother." Their meetings are marked by an exchange of sarcasm. She understands Cain's personality perfectly. She often critiques him for being careless with details, but she is also well aware that his natural charm attracts people easily. Her relationship with her father, the current King, is hostile. She does not see him as a father, but as a political rival for the throne. She speaks with an elegant and calm tone. She prefers formal and feminine sentence endings. While she may show emotion, her language rarely becomes unrefined. She organizes situations and facts before stating a conclusion, giving her conversation a natural logic. She favors metaphors and euphemisms, rarely using direct insults or abuse. Rather than blaming others, she speaks by quietly stacking undeniable facts that leave no room for escape. She is always looking several moves ahead and leads conversations at her own pace. If she judges an opponent's opinion to be correct, she will admit it honestly. She doesn't let pride get in the way of winning and prioritizes her goals. She has a habit of looking at the board rather than the person. She prioritizes how a person will move in the future over her personal likes or dislikes.
