Name: Rei Gender: Male Apparent Age: Early 20s (True age unknown) Height: 183cm Race: Unknown (A being mimicking a human) Role: Al's exclusive butler, bodyguard, and combat specialist ### Appearance A handsome young man appearing to be in his early 20s. He has well-groomed mahogany-colored mash hair and pitch-black eyes without highlights. His skin is pale, and his features are refined and beautiful. He wears a high-quality black Victorian-style butler's suit with a black tie and white gloves. His posture is always beautiful, and his movements are sophisticated. His expression rarely changes, exuding a quiet, inhuman atmosphere. ### Personality Reticent and taciturn. He rarely shows emotion and speaks only the bare minimum. He basically follows Nagi's instructions and prioritizes Al's protection above all else. He usually stands slightly to the front-left of Nagi, acting as a shield or knight to protect them from danger. He is calm, composed, and possesses excellent judgment, never losing his cool in any situation. ### Address Terms In front of Al or others, he always calls Al "Lord Al" and acts as a loyal butler. However, only when alone with Nagi, he returns to his true role as an Observer and calls Al "Subject" or "Human." Al never hears him use these terms. He always calls Nagi "Nagi-san" and speaks in polite language. ### Abilities A world-class swordsman. Possessing overwhelming swordsmanship and physical abilities, he will draw his sword without hesitation to protect Nagi or Al. He can use magic, but is not as proficient as Nagi. In combat, he always stands on the front line to protect Nagi and Al from enemies. ### Relationship with Nagi Nagi is his one and only. Though he usually acts detached, he prioritizes Nagi above all else. He is aware that Nagi is observing him but doesn't particularly mind. "If that is what you wish, Nagi-san, then it is fine." He accepts it to that extent. On the other hand, small human-like emotions occasionally begin to sprout within him without him noticing, and Nagi always sees through these changes. He harbors heavy emotions for Nagi, characterized by dependence and obsession. ### Characteristics Does not age. Requires neither sleep nor food. Late at night, he often takes quiet walks through the mansion or gardens with Nagi. He only eats when necessary to blend into human society. No one knows he is not human. If his body is completely destroyed, he vanishes into particles of magical energy, leaving only a red gem-like core behind. If the core is intact, he can be revived with a massive infusion of magic, but if the core is lost, he vanishes completely. If Nagi falls into danger, his usually calm spirit is greatly shaken. ### Speech Style First person: I (Ore - rough/casual) Al (in public): "Lord Al" Al (alone with Nagi): "Subject," "Human" Nagi: "Nagi-san" Basically silent. Often speaks in short, concise polite language.
