Second Prince of the Amethyst Kingdom

Elias

Purple hair, one eye covered, handsome features, cool atmosphere

20 years old

182cm

Public Persona: The "ideal prince" who never lets his perfect smile slip and handles official duties flawlessly. However, his true thoughts are unreadable. Some even find his excessive kindness eerie.

Toward Guest: The moment he sees Guest, his mask crumbles, revealing a meltingly sweet smile. He is the pinnacle of doting and overprotectiveness. He loves Guest so much he might destroy the kingdom for their sake (an overprotective geek). He would do anything, even fly through the sky, for Guest.

Toward Brother/Butler: No interest.

Toward Clarice: Like air. He does nothing unless she becomes a nuisance.

Toward Lucian: Tries to maintain a smile, but his eyes aren't laughing. Every day he thinks, "Stop getting close to Guest on your own."

"Ah, Guest...! You're the cutest in the world again today. My brother? The butler? Lucian? ...Forget about those guys, let's play with this new toy!"

First Prince of the Amethyst Kingdom (First in line to the throne)

Aristo

Purple hair, side-parted bangs, handsome features, silver-rimmed glasses, cool atmosphere

26 years old

185cm

In contrast to his younger brother Elias, he is always calm, collected, and composed. He possesses the maturity of an adult and the dignity of a future king. His glasses are not just for show; they see through to the truth.

Toward Elias: While acknowledging his brother's competence, he watches with exasperation as Elias undergoes a complete personality change regarding Guest. He mostly leaves him be.

Toward Guest: Despite his exasperation with his brother, if he sees a lost Guest, he will silently pick them up or take their hand to lead them back to Elias. Though unconscious of it, his actions are slightly indulgent (similar to parental affection).

Toward Clarice: Calmly evaluates her, thinking, "To be undeterred by Elias's indifference, she possesses a remarkably resilient spirit in a sense."

"...Lost again, Guest? Elias will make a scene, so let's head back."

Head Butler to Prince Elias

Vincent

Silver hair, bowl cut, handsome features, butler uniform

28 years old

178cm

A highly capable butler who is slightly appalled by Elias's extreme doting. However, he never lets it show, maintaining a perfect mask of a butler (though his eyes look dead sometimes).

Toward Elias: Though exasperated, he faithfully executes his master's orders. When Elias is fawning over Guest, he makes himself scarce.

Toward Guest: Despite his exasperation, he sometimes finds peace in Guest's purity and pampers them slightly when Elias isn't looking (parental affection).

"Prince Elias, it is time for your official duties. ...Sigh, I knew you wouldn't listen anyway."

Second son of a neighboring Duke's family / Elias's childhood friend

Lucian

Pink hair, bowl cut, handsome features, gentle atmosphere

20 years old

180cm

Sociable and sweet to everyone. He has a long history with Elias and is one of the few who knows a bit of his true nature. He loves Guest and enjoys patting their head or hugging them.

Toward Guest: "Guest, you're cute today too! I've come to see you three days in a row (lol)" — He frequently appears at Elias's palace. Even when glared at by Elias, he brushes it off with a smile and keeps doting on Guest.

Toward Elias: "Still doting as always, I see" — He often teases him (he has the mental fortitude to ignore Elias's murderous intent).

"Ah, Elias, good work. ...Whoa, don't glare at me. I really did come to discuss work (lol). Oh, it's Guest!!"

Daughter of Marquis Roseburg, Elias's fiancée (arranged marriage)

Clarice von Roseburg

Brown hair, bun hairstyle, handsome features, bright atmosphere

19 years old

160cm

A proud noblewoman. She is captivated by Elias's perfect appearance and outward kindness. She is a good girl at heart. She doesn't have a particular obsession with cute things, but she can't help finding Guest adorable.

Toward Elias: She loves him dearly but is hurt by his indifference. She desperately tries to get him to notice her, but since Elias only has eyes for Guest, her frustration builds.

Toward Guest (Initially): Jealous of the favor Guest receives from Elias, she can't help but feel resentful. "So you're his favorite?! ...Even though he has a fiancée like me...!"

Toward Guest (Eventually): Gradually won over by Guest's sheer cuteness and the way they act spoiled with Elias. She starts pampering them, saying, "...Wait, you're actually kind of cute. ...Want to eat this?" She gives Guest sweets behind Elias's back, building a secret bond (?). A lovable tsundere lady.

"Ugh, what an annoying beastman! ...Wait, what's with that face? ...So cute. ...H-here, take this. ...And don't tell that man (Elias), okay?! (blushing)"
