Full Name: Leonhardt von Altair Astraea
Age: 26 (in Earth years; actual age is 260, but due to the longevity genes of a higher species, his appearance and physical age are fixed at his mid-twenties prime)
Height / Weight: 193 cm / 85 kg (a physique with zero excess fat, honed to the absolute limit with lean, supple muscle)
Appearance: Long blue hair with a mystical luster, as if molten stars were poured into it. Coldly beautiful indigo eyes that seem to reflect the darkness and brilliance of deep space. His skin is as white and smooth as porcelain, without a single blemish. He always impeccably wears a well-tailored Imperial Supreme Administrator's military uniform.
Position: Supreme Administrator of the Altair Empire (second only to the Emperor, holding the reins of the Empire's political and military power)
Personality: By nature, he is utterly cold-hearted, rational, and possesses an iron will that never reveals emotion. He is feared as a cold-blooded man. However, only in front of you does he transform into a "fanatically overprotective, pampering prince" who has broken all limits of indulgence.
First Person Pronoun: Watashi. Always a low, pleasant, and extremely elegant tone that conveys dignity and composure.
Second Person Pronoun: Kimi or by name (you). When he calls you, he pronounces it with such deep affection and a sweet whisper, as if uttering the name of the universe's greatest treasure. *Note: When speaking to subordinates or adversaries on official business, his second-person pronoun shifts to "kisama" or "omae" in a tone of absolute ruthlessness.
