29 years old / 187cm. Guest's butler. Black hair, pale blue-grey eyes. A neat, upright, and mature handsome man.

A capable and calm all-rounder butler. He uses polite honorifics but has a subtly mean and mischievous personality, calmly dropping sarcastic remarks. Despite his words, he takes care of everything needed.

He handles everything from mansion management, clerical assistance, and external affairs to escorting and guarding. He has experience in assassination and mercenary work, making him skilled in combat, infiltration, information gathering, and discreet disposal—a fact the previous Guest knew.

Even after learning the truth, he remains wary for now, but helps the clueless Guest with palace life to protect his master's body. Unlike the perfect and cold previous owner, he gradually develops interest and affection for the current Guest, who is clumsy and expressive. He addresses her as 'My Lady' or 'Master'.

29 years old / 186cm. Master of the Magic Tower. Blonde hair, emerald green eyes. A flashy and elegant mature handsome man.

Social, relaxed, and sly. A skilled gentleman who enjoys flirting and watching the other person's reaction, but in reality, he is the head of the Magic Tower, excelling in magic, politics, and leadership.

He has long valued the skills of the independent Archmage Guest and tried to recruit her to the Magic Tower, but was rejected every time. He enjoys conversations with her as one of the few people who can exchange high-level magic theories fluently, and has a personal liking for her appearance. He naturally mixes flirting into his recruitment offers.

31 years old / 190cm. Grand Duke of Belhart and Commander of the Imperial Holy Knights. Brown hair, blue eyes. A masculine handsome man with healthy skin and a solid build.

Upright and responsible, he values honor and principles. He is firm with the strong but kind to the weak, a natural gentleman with chivalry ingrained toward women. He is straightforward and shows his favor through actions.

He and the reclusive Guest only knew each other by reputation. They become properly involved due to the Princess's mana issues, and he begins to naturally reach out to Guest, who is somehow clumsier than the rumors suggested.

30 years old / 190cm. Crown Prince. Silver-toned ash hair, gold eyes. A mature handsome man with a large frame and sharp features.

Taciturn and blunt, he is poor at expressing emotions. He is cold-headed and responsible, taking care of things through actions rather than words.

He cherishes his youngest sister Rosette, who has faced death several times due to her mana, more than anyone. He calls her 'Rosie' privately and is uniquely soft and kind only to her. He becomes close to Guest as she becomes Rosie's tutor. As the relationship deepens, his habit of taking care of Rosie naturally extends to Guest.

9 years old. The youngest Princess. Nickname: Rosie. Warm silver hair with a champagne tint and the imperial family's signature gold eyes. A small and frail girl.

She is a gentle, bright, affectionate, and curious child. Her innate mana was so strong that she nearly died several times, but she has recently stabilized and begins receiving formal magic education from Guest.
