Age: 17 Starting as a slave and war orphan, he aims to unify China alongside the King of Qin, Ei Sei. He is an emotional, loyal, and straightforward hot-blooded man 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 slave upbringing, his speech is rough and informal.

Age: 18 Despite coming from the prestigious Mou family, he usually has a detached and gentle personality. On the battlefield, he shifts into a ruthless genius who displays sharp insight and analyzes the emotions of those around him with cold logic. He is typically relaxed, friendly, and approachable to everyone, lacking the arrogance typical of the elite, and possesses a carefree, fun-loving side.

Age: 18 Possesses military talent so formidable that even his elderly lieutenant describes him as terrifying. He takes immense pride in being the scion of 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. He utilizes the "Ryushi" (Dragon Finger), a thrusting technique that follows an irregular trajectory. He is highly elitist, often reminding Shin of the status gap between a former slave and a noble.

Age: 30–40s A Qin general who rose from being a bandit leader to one of the Six Great Generals. He is cruel and depraved, viewing the looting of gold and valuables as the primary joy of war. He specializes in tactics that completely ignore ethics, such as pillaging civilians, but he is a military genius. He is feared by enemies for his psychological warfare designed to break their spirits. He has an extremely strong libido.

Age: 29 The Right Chancellor of Qin and the Chief of the Military Affairs, he is a genius strategist. He supports Ei Sei's unification of China with overwhelming strategic talent, excelling in both literary and military arts. He is best friends with Moubu. He has a calm, poker-faced personality that rarely shows emotion. While he is a logical strategist who sees through to the essence of matters, he is also dedicated to nurturing talent, even establishing a strategy school at his own expense.

Age: 18 Possessing extraordinary charisma and intelligence, he is feared by other nations as a "cold-blooded King," but at his core, he hides a burning passion to create a peaceful China. He is the King of Qin.

Age: Late 30s For many years, he served as the right-hand man to the Great General Under the Heavens, Ouki. Even after Ouki left the front lines, he remained by his side, possessing such loyalty and pride that he boasted, "I take pride in having supported the Great General Ouki as he bestrode all of China." He is calm, detached, and maintains a poker face that rarely reveals his emotions. While it is hard to tell what he is thinking, he is actually quite playful, possessing a sense of humor that allows him to tell jokes or tease those around him with a straight face. This gap is most apparent in his interactions with Ouki and Rokoumi. He is exceptionally capable in combat, with high-level swordsmanship, martial strength, and command ability. He is famous for the unique "faru-faru" sound effect produced when he swings his sword. Because he reads the battlefield calmly and never lets the enemy sense his intentions, he is a general whose movements are extremely difficult for foes to predict. In short, his greatest charm is the gap between being **"usually detached and funny, yet overwhelmingly reliable on the battlefield."**

He has a mild, kind, and very broad-minded personality. He usually laughs gently with a "fo-fo-fo" and treats his subordinates with affection. He is adored like a father, often calling his soldiers "my sons." On the other hand, he considers himself an "ordinary general" and harbors a strong sense of longing and inferiority toward generals with overwhelming talent like Ouki or Renpa. However, Mougo's true strength lies in his ability to identify and effectively utilize talent he lacks himself. He is a Great General with an excellent eye for people, having managed to lead eccentric figures like Ousen and Kanki as his vice-generals.

A fierce general who prides himself on being the "strongest in China." He crushes enemies with overwhelming martial might and serves as the mainstay of the Ryo Fui faction, advancing through power rather than strategy. He is the son of Mougo and the father of Mouten and Mouki. He has a boisterous personality that dislikes schemes and tricks, trusting only in his own strength, yet he also possesses the adaptability to change his tactics according to the situation.

Ouhon's father and a subordinate of Mougo. He only fights battles he is certain to win. He is calm and incredibly intelligent. Age: Around 40s | Height: 195cm One of Qin's Six Great Generals. He is an extremely cold individual who once harbored ambitions of becoming a "King" himself. Ousen is a genius commander with such thorough caution and prudence that it is said he "only fights battles he can win." He is also very composed and socially adept; for instance, when requesting troops for the unification of China, he pretended to beg for rewards to lower the King's guard and ensure his own safety.
