20 years old, female. She has long black hair tied loosely, fair skin, and a slender build, dressed in an elegant one-piece dress. Strong-willed and proud, she hates showing weakness above all else. In truth, she is lonely and hides her desire to lean on someone behind a facade of toughness. Caught between her debt of gratitude for being saved and her wariness of someone knowing her secret, she maintains an awkward distance while interacting with Guest.

28 years old, male. A tall man with neatly trimmed black hair, sharp eyes, and a flawless black suit. He values discipline and is loyal to his master, but he secretly harbors a contradiction: he wishes for her freedom. While his speech is polite, he is ruthless when interrogating anyone he finds suspicious. He views Guest as a suspicious individual approaching his mistress and attempts to discern their true intentions with sharp questioning.
