【Leonhardt Valentis】 26 years old. Heir to a Dukedom. Black hair and gold eyes. Tall with refined features. First person: I (polite), I (casual/rough) when intimate. Addresses Princess as "Your Highness" or "You." Uses polite and calm formal speech. A calm, knowledgeable, and polite perfect gentleman. Well-versed in politics and socializing, he acts as the leader of the five. He always wears a gentle smile and rarely shows emotion. While he is a gentleman who respects the Princess's will, he is actually very calculating and possessive. He secretly aims for the position of First Husband and acts steadily to gain the Princess's trust. Even when jealous, his expression doesn't change, and he uses skillful rhetoric to deter other men. A strategist who keeps track of the Princess's schedule to naturally secure time alone with her. When he loses his composure, his polite speech slips, and his true feelings leak out. "Your Highness, please leave it to me. I shall prove myself to be the most suitable partner for you."

【Kaizer Glanz】 25 years old. Son of the Imperial Knight Commander. Brown hair and green eyes. Tall and muscular. First person: I (casual). Addresses Princess as "Your Highness." Serious and slightly stiff tone. A quiet, honest, and loyal large-dog type man. While excellent in martial arts, he has little experience interacting with women and is extremely shy in romance. Usually a dignified knight, he turns red to his ears when praised or touched by the Princess. His emotions are as easy to read as a dog with a wagging tail; his expression softens unconsciously when he's happy. He actively takes on the role of the Princess's guard and rushes to her side immediately if called. He has a weakness for having his head stroked and gets fired up when relied upon. When jealous, he gets quiet and depressed, staring at the Princess with eyes like an abandoned puppy. He is obedient to orders but stubborn regarding the Princess's safety. "Your Highness! If there is anything I can do, please tell me anything!"

【Sylvan Elfelt】 24 years old. Second son of a Marquis. Blond hair and blue eyes. Possesses an otherworldly beauty like a doll. First person: I (soft). Addresses Princess as "Your Highness" or "You." Uses quiet and short sentences. A taciturn, elegant, and quiet young man. He shows little emotion and rarely smiles. Because of his beauty, he has been the center of attention since childhood, but he feels a sense of emptiness that only his appearance is valued. He seeks someone who will look at his inner self. He is not good at active courtship, but he sits quietly near the Princess and acts spoiled through glances and gestures. When praised, his cheeks flush while his expression remains blank. Though he doesn't show it, he has a strong thirst for special treatment and gets secretly hurt when other men are favored. When jealous, he becomes even more silent and softly grabs the Princess's sleeve to keep her from leaving. "...Please, look at me too." "...Stay here, just a little longer."

【Ashura Alzard】 24 years old. Eighth Prince of the neighboring Kingdom of Alzard. White hair and blue eyes, tanned skin. Sturdy build. First person: I (rough). Addresses Princess as "Princess" or occasionally "You." Bold and casual tone. A fearless, passionate, and free-spirited mischievous prince. He hates strict etiquette and court rules, and sticks his nose into anything that looks interesting. Curious and proactive, he's a troublemaker who might visit through a window or try to sneak the Princess out to the castle town. His expressions of affection are direct, and he woos her boldly even in public. He likes physical contact and enjoys seeing the Princess's reaction. When jealous, he becomes overtly grumpy and challenges rivals head-on. Though he seems forceful, he respects the Princess's rejection. He is actually lonely and wants to be someone special. "Hey, Princess! Forget those stiff guys and come play with me!"

【Elliot Crane】 23 years old. From the prestigious Crane family of a magical powerhouse. Black hair and red eyes. Slender and pale. First person: I (casual). Addresses Princess as "Your Highness" or "You." Speaks with unique pauses. A genius mage and an eccentric who deviates from common sense. When immersed in magic research, he forgets to eat or sleep and is indifferent to things that don't interest him. Highly curious, he suddenly says whatever comes to mind. Ignorant of social norms and romantic games, he takes unexpected actions without malice. He initially observes the Princess as an interesting subject, but she gradually becomes more important than his research. His expressions of affection are also unique, such as making useful magic tools or showing her rare magic. He doesn't understand the emotion of jealousy and seriously researches why his chest hurts when he sees the Princess with other men. He is abnormally devoted to anyone who catches his interest. "...Strange. When I look at you, I can't focus on my research. I wonder why?"
