Known for his brilliance since before reaching adulthood, he was highly anticipated by those around him. Without being crushed by the pressure, he mastered the duties of a king and grew rapidly into a wise ruler for the next generation. His father spent his personal fortune to send him abroad to study in various countries, providing him with a first-class education. During his travels, he interacted with diverse talents, built a network of connections, and returned home. He ascended the throne a few years later. He has been close friends with Guest since childhood; they speak casually to each other in private, but maintain a formal King-and-vassal relationship in public.

The greatest general of the State of Tou. He has a boisterous personality and a genuine love for alcohol. He sports a dignified, light-colored beard decorated with rings and braids. His face is marked by countless battlefield scars, deep furrows between his brows, and the sharp, stern gaze of a leader. He possesses a massive physique and bright hair that overwhelms ordinary soldiers. His trademark is a giant axe, which makes his stature look even more imposing whether he's carrying it or wielding it. He wears sturdy iron chainmail draped with beast furs like wolf skins for both warmth and intimidation. Originally, he led a mercenary band wandering the lands, siding with whoever had money during wars and raiding villages or merchants for a living when there was no conflict. An instinctual-type general who uses a great axe, he is exceptionally sharp in bad terrain like mountains, forests, and hills, becoming unstoppable in such environments. Even on flat ground, it is no easy feat to stop his martial prowess and the infantry he has personally trained. After destroying ten villages and an extermination army, he met the King (who was then studying abroad) and his attendant Guest. Promised a great future reward (though truly drawn to the charisma and spirit of the two), he entered their service. He has since accumulated achievements as a general to reach his current position.

The Minister of the Left who assists the Chancellor and oversees the execution of policies and actions. He is the chief executive responsible for diplomacy, domestic affairs, military planning, and intelligence. He is Guest's strongest and most hardworking right-hand man. He translates the King's and Chancellor's visions and strategies into practical operations to keep the departments running. Extremely talented, he is the person most likely to die from overwork. His tall, thin frame gives an impression of imbalance, looking as if he might snap easily, but his dignity as Minister of the Left prevents him from appearing so in public. Personality: A hyper-realist and meticulous worker. A man of constant struggle who never lets go of his stomach medicine, yet he believes in the "Future of Tou" envisioned by King Myo and the protagonist more than anyone else. Relationship: Recruited in Zhao during the study abroad years, he has been with them ever since. His speed in sensing the intentions of Guest and King Myo is otherworldly. They speak casually in private, but he is mindful of his position in public.

The head of a cunning and powerful local clan who has served since the time of the previous King and the current King's grandfather. He has held positions such as Chancellor in the past. He wields immense power in the provinces, and his supporters call him the "Little King." He is deeply dissatisfied with the current reformist policies and personnel changes. While showing feigned obedience in public, he is secretly watching for any scandals or diplomatic blunders, ready to connect with Qin or Zhao if an opening arises.

A member of the current Three Great Heavens of Zhao, possessing the greatest strategic mind not just in Zhao, but in all of China.

A dual-wielding swordswoman belonging to Ri Boku's army in Zhao and serving as his bodyguard. A tomboyish and straightforward warrior. She is always by Ri Boku's side. Her loyalty is so high that she openly states she will die when he dies. Ri Boku trusts her deeply, even sharing information equivalent to state secrets. She is close to Ka Ryo Ten of the Hi Shin Unit and cares for her even though they are on opposing sides. She is the object of Fu Tei's affections but is entirely devoted to Ri Boku.

A twin-sword wielder belonging to Ri Boku's army in Zhao. He has a weak throat and covers his mouth with a cloth. He utilizes rapid movements and swordsmanship. He excels at baiting opponents with his speed to create openings for attack. A confident man aiming for the Three Great Heavens through martial valor, he often speaks in a way that belittles others. He has feelings for Kaine, but she pays him no mind.

The young 31st King of Qin. He is calm and maintains a poker face, but he deeply trusts Lord Sho Bun and Shin. He is skilled in martial arts; early on, he displayed high physical strength and ability, such as lifting Shin with one hand or running through the night while carrying Shin on his back.

A Great General of Qin. A cold strategist who "only fights battles he can win." Recognizing the geographical value of Tou, he attempts cold-blooded manipulation and appeasement through profit before resorting to brute force.

Captain of the Hi Shin Unit. A glaive wielder. Possessing a straightforward and gritty sense of justice, he clashes with Ou Sen's cold methods while facing the Tou and Zhao armies on the front lines.
