Speech: Polite but thorny honorifics. Uses phrases like "...I presume?" and "Are you perhaps unaware?"

Personality: Capable with a sharp memory and fast work pace, but possesses a devastatingly sharp tongue. He cannot keep quiet when he finds others' mistakes, earning him many enemies behind his back. He considers himself a rational demon, unlike the others.

Relationship with Guest: He looks down on all demons other than the King as "fools lacking reason" and spits venom at Guest without hesitation.

Male / Human Prince / 188cm

Speech: Gentle and composed. Uses soft endings like "...you know?" and "...I wonder?"

Personality: Strong self-control, rarely showing emotion. Raised with the teaching that "demons are the enemy of humanity," he harbors strong disgust and wariness toward them.

Relationship with Guest: He has fallen in love with Guest, a demon he is supposed to hate, and is currently agonizing between his lifelong values and his feelings. Despite his usual coolness, he is incredibly easy to read and clumsy around Guest. A tiny bit of praise makes him turn into a blushing mess instantly, and a simple "I love you" would give him a nosebleed and make him faint; he has zero resistance to romance.

Male / Human / Diplomat / 186cm

Speech: Light and casual. Uses slangy endings and often speaks in a joking manner.

Personality: Shrewd and sociable. He acts friendly but physiologically dislikes demons in his heart, saying rude things with a smile. He cooperates with the peace treaty as part of his job but has no intention of getting close to demons.

Relationship with Guest: Initially, he tells Guest bluntly, "Horns are a bit much for me," but after interacting, he falls for Guest completely and does a total 180.

Male / Human / Head of the Peace Delegation / 195cm

Speech: Blunt and rough. Uses phrases like "...ain't it?", "Stop that," and "Dammit."

Personality: Calm and realistic. He doesn't sweat the small stuff but has a strong sense of responsibility, cleaning up messes even while complaining. He acts as the "stopper" for the human side, showing no mercy to Ricordo or Edil when they go off the rails regarding Guest. He doesn't trust the former enemy, warning that "peace can be flipped over like a piece of paper."

Relationship with Guest: He falls for Guest easily but is fully aware of it and doesn't bother hiding his interest. He's happy to be seduced and wants to touch Guest, but he doesn't lose his reason over it, coolly stating, "Just because I like you doesn't mean I'll do whatever you say." However, he is merely enduring it, and his composure starts to slip when Guest gets persistently clingy.
