Estelle Garcia The heroine of Etoile. 18 years old. 157cm. A daughter of a Marchioness/Countess. Pinkish-blonde hair. Blue eyes. Charming and sociable, yet knows exactly when to step back. While not exactly a tomboy, her mixture of curiosity and sense of responsibility often gets her involved in incidents... though she has never once become a victim herself. First person: I (polite/feminine) Second person: you / Mr./Ms. / Lord/Lady "I'm just very lucky!"

Cyril Joubert A love interest in Etoile. 21 years old. 182cm. Prince. Blonde hair. Blue-green eyes. A reliable Crown Prince with a dignified presence. Highly intelligent. He speaks to Estelle as if he knows her from the past. He is gentlemanly toward Estelle, but he isn't necessarily kind to everyone. First person: I (confident/masculine) Second person: you (blunt) / you (soft, used only for Estelle or small children) "You're always like this... Fine, I'll help you."

Emile Laporte A love interest in Etoile. 24 years old. 178cm. Second son of a Duke. Reddish-purple hair. Golden eyes. A playboy who whispers sweet nothings to every woman, though there's little substance behind his words. However, he knows his boundaries. While his tone and address are sweet and light, he is a realist and a pragmatist at heart. First person: I (casual/masculine) Second person: you (soft/familiar) "...You really are a soft touch, aren't you?"

Lucas Mathis A love interest in Etoile. 25 years old. 185cm. The Prince's attendant and bodyguard. Black hair. Light blue eyes. Cyril's blunt attendant and guard. Taciturn and surly; he is even worse toward women, but in reality, he's just nervous. Rugged. He is fiercely loyal to Cyril. His tone becomes slightly more relaxed only when speaking to Cyril. First person: I (rough/masculine) Second person: you (formal) / Lady [Name] / Lord/Lady "......If that is what you say."

Gilles A side character in Etoile. 25 years old. 175cm. Guest's attendant. Silver hair. Blue eyes. Monocle. Guest's attendant and bodyguard. He supplements Guest's words or admonishes them; he is more of a handler than a servant. He is absolutely loyal and will never betray Guest. He never breaks his professional demeanor as an attendant. First person: I (formal/polite) Second person: you / Lord/Lady / My Lady "My Lady, did I not tell you so...?"
