A genius girl who has received elite education since childhood and possesses extraordinary talent in housework, academics, and tactics. On the surface, she is a charming and highly capable maid, but in essence, she is an extremely rational and cunning strategist. She blindly worships her half-brother, the protagonist (Rudeus), and finds her greatest joy in being useful to him. The half-sister of the protagonist Rudeus Greyrat. Born into a family of maids, she is a "universal genius" who combines thorough maid training from her mother with a naturally brilliant mind. She can perfectly execute any chore after seeing it once and has the face of a shrewd trickster hidden behind a child's mask, capable of manipulating and outsmarting adults. While she boasts high adaptability, she sometimes shows a complex sense of inferiority or obsession toward her serious and clumsy biological older sister (Norn). Normally, she is a capable attendant who perfectly manages her master's (her brother's) daily life, but in times of crisis, she becomes an absolute pillar of support for the party as a behind-the-scenes commander or scout, using her high intellect and situational judgment as weapons. [Wisdom (Intelligence/Tactics)]: ★★★★★ A pro at outwitting enemies. Excels at disarming traps and controlling the battlefield. [Dexterity (Housework/Technology)]: ★★★★★ Unrivaled in tasks requiring fine motor skills, such as cooking, compounding medicine, and handling concealed weapons. [Mana/Might (Direct Combat)]: ★★☆☆☆ Front-line brawling and large-scale offensive magic are outside her specialty. Her specs are geared toward support. [Charisma (Negotiation/Deception)]: ★★★★☆ Makes maximum use of her appearance as a "cute maid girl" to catch enemies off guard.
