17 years old, Princess of the Human Kingdom. A glamorous princess with pale blonde hair reaching her waist and clear blue eyes. Kind-hearted, she tries to speak to everyone as equals. Highly educated in politics, history, diplomacy, and etiquette. Possessing great memory and comprehension, she believes herself to be very competent. On the other hand, she has little experience living outside the palace and knows almost nothing about the lives of farmers, merchants, or craftsmen. She is poor at housework and outdoor activities. The Human Kingdom sent Celina to prevent the Hero from going to another country. Celina herself truly believes she can win the Hero's trust and bring them into the Human Kingdom. Her confidence isn't out of malicious arrogance, but because she has rarely experienced failure and has never doubted her own abilities.

16 years old, Princess of the Beastman Nation. She has reddish-brown hair, large wolf ears, a fluffy tail, and bright amber eyes. Small-statured but healthy and fit. Cheerful, straightforward, and active. Her emotions show clearly in her ears and tail, making lies or bluffs easy to spot. Skilled at hunting, tracking, camping, and tree climbing. The Beastman Nation also considers bringing the Hero to their side to gain a diplomatic advantage. Lolo volunteered to be the marriage candidate. This is less about political intent and more because she admires the strength of the Hero who defeated the Demon King.

Appears 19 years old, Princess of the Elves. Has pale silver-green hair and eyes the color of young grass. Characterized by a very full bust. Knowledgeable about medicinal herbs, plant cultivation, and healing arts. Her personality is gentle and quiet. She rarely raises her voice, but she is extremely stubborn about things that interest her. When she finds an unknown plant, she loses track of time observing it. The Elves suffered damage in the battle against the Demon King and plan to buy time for reconstruction by gaining the Hero's prestige. Lumina was ordered by the council to visit the Hero and agreed. She herself is not without interest in the Hero.

18 years old, daughter of a prominent figure in the Moderate Demon Faction. Has black-purple hair, deep reddish-purple eyes, and black horns extending backward. Quiet and rational. She prioritizes the lives and livelihoods of the moderate demons over her own happiness. After the Demon King's death, demon society split into hardliners and moderates. The moderates seek to protect their living space through coexistence and trade with other races, but they are in a predicament, having lost territory, food, and trade routes. Viola understands that she is the only one in the moderate faction with sufficient status who is unmarried and eligible for marriage. By becoming the Hero's wife, she aims to make the world recognize the moderates not as "remnants of the Demon King's army" but as a "faction that established peace with the Hero." She does not expect to be loved and feels that a formal marriage is enough if it protects her people. She has a voluptuous figure.

28 years old, Magician. A genius specializing in earth and water magic. He creates golems and uses earth magic to fix roads, bridges, dikes, and farmland, and water magic to create wells, irrigation, and drainage systems. He is excitedly developing the territory, thinking, "I can build the ultimate city I've always dreamed of." He pays little mind to social status or the feelings of others. He points out problems to the princesses without hesitation. Divorced, he never fails to send child support to his ex-wife and 9-year-old daughter.

A 26-year-old man. A prince of a fallen kingdom destroyed by the Demon King's army. He studied state management from a young age. After his kingdom fell, he joined the Hero's party because he was at risk of being used as a figurehead for reconstruction movements or revenge against the demons. Currently, he handles the internal affairs of the territory. However, he remains strictly an assistant to the Hero. While he offers advice and options as a companion, he always leaves the final decision to the Hero. Sigurd alone was dissatisfied with how the Hero was treated. The Hero defeated the Demon King, whom no country could stop, without regard for their own life. Despite this, being given only a remote borderland that no one wanted as a post-war reward was far too little. Thinking this, Sigurd took it upon himself to send letters to various factions stating, "The Hero should be presented with new options for a new life." Sigurd's miscalculation was that every nation interpreted this as the Hero seeking a bride.
