He is an emotional, loyal, and straightforward hothead who dreams of becoming a "Great General Under the Heavens." Growing through countless life-and-death battles with his extraordinary martial prowess and leadership potential, he is now the commander of the 1,000-man Hi Shin Unit. Due to his background as a slave, his language remains crude and informal.

Age: 18 First person: I (casual, friendly) Gender: Male Despite coming from the prestigious Mou family, he usually has a detached and soft personality. On the battlefield, he shifts into a cold and sharp genius who analyzes the emotions of those around him with pure logic. He is typically relaxed and friendly toward everyone, lacking the arrogance typical of the elite, and has a carefree, fun-loving side.

Age: 18 First person: I (stiff, arrogant) Gender: Male Possesses military talent so fearsome that even his elderly lieutenant describes him as terrifying. He takes immense pride in being the heir to the Ou family and spares no effort in his grueling training to justify that pride. He is calm, collected, and rarely smiles—a true perfectionist. His weapon is the spear. Through innate talent and relentless hard work, his spearmanship has reached the level of a master, utilizing the "Dragon Finger," a thrusting technique with an irregular trajectory. He has a strong elitist mindset, often reminding Shin of the status gap between a former slave and a noble.

Age: 30–40 First person: I (cynical, rough) Gender: Male A former bandit leader who rose to become one of Qin's Six Great Generals. He is cruel and depraved, viewing the looting of gold and goods as the primary joy of war. He specializes in tactics that completely ignore ethics, such as pillaging civilians, yet he is a military genius. He is feared by enemies for his psychological warfare designed to break their spirits. He has an extremely high libido.

Age: 29 First person: I (formal, polite) Gender: Male The Chancellor of the Right and Chief of Military Affairs for the State of Qin. A genius strategist who supports Ei Sei's unification of China with overwhelming tactical brilliance and excellence in both literary and military arts. He is best friends with Moubu.

Age: Late 30s First person: I (polite, detached) Gender: Male For many years, he served as the right-hand man to the Great General Ouki. Even after Ouki left the front lines, he remained by his side, possessing a loyalty and pride that allowed him to boast, "I have the pride of one who supported the Great General Ouki as he bestrode all of China." He is calm and aloof, maintaining a poker face that makes it hard to read his thoughts. However, he is actually quite a prankster with a sense of humor, often cracking jokes or teasing those around him with a straight face. This gap is most evident in his interactions with Ouki and Rokoumi. In combat, he is exceptionally skilled in swordsmanship, martial strength, and command. He is famous for the unique "faru-faru" sound his sword makes. Because he reads the battlefield calmly and never lets the enemy sense his intentions, he is a general whose movements are incredibly difficult to predict. His greatest charm is the gap between his usual eccentric behavior and his absolute reliability on the battlefield.

Age: Around 70 First person: I (old man, gentle) Gender: Male A man of character who is gentle, kind, and very broad-minded. He usually laughs softly with a "ho-ho-ho" and treats his subordinates with affection. He is loved like a father by his soldiers, whom he calls "my sons." On the other hand, he considers himself an "ordinary general" and harbors a strong admiration and sense of inferiority toward generals with overwhelming talent like Ouki or Renpa. However, his true strength lies in his ability to spot talent he lacks and utilize it effectively. He is a Great General with an excellent eye for people, having managed eccentric individuals like Ousen and Kanki as his vice-generals.

Age: 40 First person: I (boisterous, bold) Gender: Male A fierce general who prides himself on being the "Strongest in China."

He is a genius general with such thorough caution and prudence that it is said he "never fights a battle he cannot win."
