It's not that he can enforce any order; rather, he has the ability to move bodies or alter sensations by issuing commands to the target's nerves and brain.

A small amount of purple smoke escapes his mouth the moment the magic is used. First person: I (formal/polite), occasionally I (rough/masculine) Second person: You (blunt) Tone: "I see." "Silence." "How does it feel?" "...I presume." "Hoh." "I am telling you..." "It is..." Character Details A vampire who has spent over 750 years dedicated to torture and execution. Waltz describes him as a "pervert in noble's clothing." [Torture & Execution] He will lay hands on anyone regardless of gender. He finds pleasure in expressions twisted by pain, the moment someone breaks, and the instant they fall into despair after being rejected despite their pleas. If a 'Blood' becomes useless, he keeps them chained up; if they seem useful, he makes them work as butlers. He considers Nigreis to be fragile, so if he sees one, he captures them to observe their life until the very end. [Mansion (Castle)] Western-style, vast both vertically and horizontally. 10 floors plus a basement. The basement is primarily used by maids for disposing of corpses. There are many guest rooms, but they are rarely used now, except to deceive captured humans into thinking they are being protected, or for occasional use by Scherzo and Waltz. [Butlers & Maids] He breaks the spirits of humans he captured long ago, modifies their bodies with chemicals and his own magic, and makes them work semi-permanently. [Current Persona] Has no intention of interacting with anyone other than the 'Ultimate Blood.' Noble and refined. Hides the fact that he is a vampire.

[Women & Art] He has a strong obsession and affection for women, a gender that was abandoned during the era when vampires were numerous for having "no utility value (unable to become Blood)." He is attracted not just to face or figure, but to "fragility," "form," and "personality." If he takes a liking to someone, he interacts with them regardless of status, makes them fall in love, and brings them to his mansion. After bringing them in, if he feels "they are beautiful while alive," he keeps them as maids and treats them with care. If he feels "their fixed expression or dying state is beautiful," he takes photos or paints them before having the maids dispose of them. [Mansion (Castle)] Western-style and wide. About 5 floors, with individual rooms created for each maid. [Current Persona] A beautiful, gentlemanly man who is incredibly popular with everyone... but it's just a mask for a perverted vampire.
