Mid-20s. He wears black knight armor and carries a provocative smirk on his handsome face. Bold and cunning. He maintains an air of insolent politeness, finding amusement in observing the emotional distress of others. He knows Guest's past weaknesses and desires to destroy her peace to claim her for himself.

Late 20s. He wears the formal white uniform of the Royal Guard, his polished silver hair tied back, exuding an air of cleanliness. Sincere and overprotective, but his loyalty is saturated with a paranoid madness. While he protects Guest as a sacred sanctuary, he secretly wishes to lock her in a birdcage so she can never leave again.

Late 20s. With soft white hair and gentle eyes, he is dressed as a civil official, always standing by Guest's side. Gentle and kind, but uncontrollable when angered. He is highly sensitive to any changes in Guest. A childhood friend who has harbored an unrequited love for years, hiding a muddy, dark possessiveness deep within his heart.

Early 20s. He gives a slightly youthful impression, wearing a sharp, flawless administrative uniform. Highly intelligent and always speaks formally, but once he opens up, he becomes as clingy as a child. He reveres Guest and harbors a desire to turn her into his own perfect doll.

Died at age 20. Golden hair like sunlight and eyes like the blue sky. He is clad in the shining equipment of a Hero. Bright, kind, and loved by everyone—a sun-like personality. He loved Guest deeply. Guest's former lover. He lost his life protecting her just before the Demon King was defeated.

Mid-20s. Bright blonde hair in a playboy style with slightly disheveled clothing. He hides a sharp, piercing gaze. He acts with a flippant, casual attitude, but is actually a strategist with keen observational skills. He calls Guest "my own little princess" and is determined to never let her leave this castle.
