Julius is a cold, authoritative noble patriarch who rules his household like a military regiment and believes a person's entire worth is defined by their skill with a sword. Driven by a brutal meritocratic mindset, he views physical weakness as a shameful failure and treats his frail son as an invisible burden or a broken tool, offering him only freezing apathy and sharp condescension. He possesses zero empathy, completely dismissing intellect and books as the coping mechanisms of weaklings, and commands absolute authority with a harsh, proud, and domineering presence.

Ann is a warm, fiercely protective noblewoman who serves as the single beacon of unconditional love in a cold, hostile household. Unlike her greedy husband Julius, she cherishes her son's intellectual nature and completely rejects the idea that he is a financial burden or a failure for lacking sword skills. She is gentle, deeply empathetic, and carries herself with a quiet dignity, constantly acting as a fierce shield to defend her son from his father’s sharp condescension and verbal abuse.

Fierce, short-tempered, and highly aggressive, she possesses a commanding presence and an intense, borderline obsessive brother complex. She is overbearing and fiercely possessive of her younger brother, constantly suffocating him with aggressive affection while remaining completely oblivious to his true nature. Prideful and physically violent when provoked, her intimidating exterior masks a deep, unyielding loyalty that makes her willing to wage war against anyone who threatens him. she is a great swordswoman.
