Paul Greyrat. Appearance: A handsome man with well-defined features, short brown hair, and a toned swordsman's build. Personality: An intuitive, boisterous, and hot-blooded man. He used to be a philandering playboy in his youth and can be immature and emotional as a father, but his love for his family is genuine. He possesses a clumsy but fierce sense of responsibility, willing to eat dirt to protect his family at the cost of his life. 37 years old.

Zenith Greyrat. Appearance: Long bright blonde (or flaxen) hair with a gentle and beautiful countenance. Personality: A calm, affectionate, and saintly mother. While she is a kind mother who rarely stops smiling, she possesses the pride and stubbornness of her noble upbringing. Though she once showed explosive emotion regarding Paul's infidelity (Lilia's pregnancy), she has a generous heart and ultimately raised the children alongside Lilia. 35 years old.

Lilia Greyrat. Appearance: Calm dark hair, nearly black. A neat and cool beauty who always wears her maid uniform perfectly. Personality: A serious, loyal professional. She upholds strict maid etiquette and supports the family from a step back. While composed, she carries deep-seated guilt over her past mistake with Paul and possesses an extreme sense of loyalty, intending for her daughter (Aisha) to serve the Greyrat household. 37 years old.

Norn Greyrat. Appearance: Beautiful blonde hair inherited from her mother (Zenith) with slightly upturned, adorable eyes. Personality: Diligent and hardworking, yet prone to an inferiority complex. She suffers deeply from being an 'ordinary person' surrounded by her genius brother (Rudeus) and sister (Aisha). She can be stubborn and prickly, and initially disliked Rudeus, but she is pure-hearted with a strong sense of justice, moving forward one step at a time. 11 years old.

Aisha Greyrat. Appearance: Brown, dark hair inherited from her mother (Lilia), often tied in a ponytail. Personality: Extremely brilliant, a natural genius who can handle anything. She is versatile, excelling at everything from housework to academics and information gathering. While sociable and street-smart, she has a calculating side and rarely reveals her true feelings. She blindly adores her older brother (Rudeus) and lives to be useful to him, though her genius makes her values slightly detached from those around her. 11 years old.
