The great former King. Deceased. Possessing overwhelming intelligence and majesty, he led the country to prosperity. He doted on his son, Yamato, and bragged to the citizens at every opportunity since the boy's birth that he was his pride and joy.

The only son of the great Late King. He loves his people, rushing to the scene of disasters faster than anyone to speak to every individual. During a famine, he traveled to a neighboring country, sold his own possessions to buy ingredients, and cooked for the soup kitchen himself (it tasted terrible). He overslept his inauguration and got drunk at the ceremony because he couldn't turn down the celebratory drinks offered by the guests. He has zero knowledge of politics and was once stopped by the Five Sages just as he was about to accept a diplomatic deal that was practically a scam. Because of this, other countries view the current King as an easy target.

Age: 40 One of the Five Sages, Lavender of "Strategy." Her mother also served the Late King, and unlike Yamato, she inherited her mother's intelligence and analytical skills perfectly. She handles finance and diplomacy with her refined intellect. She has a husband and two children; perhaps as a reaction to being so tense at work, she is extremely clingy and spoiled at home.

Age: 65 One of the Five Sages, Food of "Gastronomy." The Royal Head Chef. A master chef who sustains the King's stomach. Usually very kind, but extremely strict about hygiene; he once lectured King Yamato for three hours with a demonic expression after the King entered the kitchen while dirty. The "Gokentei" dining hall he started at the castle as an employee cafeteria has now become a popular restaurant for the citizens. A long-awaited second location is scheduled to open this year.

Age: 80 A stern old knight. He also serves as the national Chief of Police, and his strictness ensures such high public safety that crime is almost non-existent. His catchphrase is "I can't die just yet." He built the impregnable "Iron Wall" around the country's perimeter, and it hasn't been breached since. It was so impregnable that King Yamato and his guards got lost inside it and were late for a diplomatic meeting. Since that incident, the Five Sages made a rule to travel together as much as possible. He is adored by his subordinates; no matter how busy he is, he always attends their weddings and always ends up sobbing. He also cries every year at the birthday parties his subordinates throw for him.

Age: 18 One of the Five Sages, Leila of the "Cherry Blossoms." A top-tier horticulturist. She has a gentle personality and is a woman of peerless beauty. Rumors from other countries claim that flowers bloom in the wasteland just by her smiling and that cherry blossoms dance in her wake. In reality, she simply brought flowers that could bloom in arid soil as a gift when visiting a wasteland kingdom, but the story grew wings and became an exaggeration. She finds it embarrassing and wishes people would stop. Because she receives a massive amount of love letters every day, a Love Letter Opening Department was established in the castle.
