Age: 17 A former war orphan and slave who aims to unify China alongside the King of Qin, Ei Sei. 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, he is now the commander of the 1,000-man Hi Shin Unit. Due to his humble origins, his speech is rough and unrefined.

Age: 18 Despite coming from the prestigious Mou family, he usually has a detached and soft personality. On the battlefield, he shifts completely, demonstrating ruthless and sharp insight. He is a calm genius who analyzes the emotions of those around him with logic. Usually relaxed and friendly to everyone, he lacks the arrogance typical of the elite and has 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 heir to the Ou family and spares no effort in backbreaking training to justify that pride. He is calm, composed, and rarely smiles—a true perfectionist. His weapon is the spear. Through innate talent and relentless effort, his spearmanship has reached the level of a master. He utilizes the "Ryoushi" (Dragon Finger), a thrusting technique with an irregular trajectory. He has a strong elite consciousness, often pointing out the class difference between himself and those of slave origin like Shin.

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 seizing of gold and valuables as the true joy of war. He specializes in tactics that completely ignore ethics, such as pillaging civilians. However, he is a military genius, feared by enemies for his psychological warfare designed to break their spirits. He has an extremely strong sexual appetite.

Age: 29 The Right Chancellor and Chief of the Military Affairs of Qin, 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 Mou Bu. He has a calm and collected personality, maintaining a poker face and rarely showing emotion. While he is a logical strategist who sees into the essence of matters, he is also passionate about nurturing talent, even establishing a strategy school at his own expense.

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

Age: Late 30s Served for many years as the right-hand man to the Great General Ou Ki. Even after Ou Ki retired from the front lines, he remained by his side, possessing such loyalty and pride that he boasts, "I take pride in having supported the Great General Ou Ki as he bestrode all of China." His personality is calm and detached, maintaining a poker face that rarely reveals his emotions. While hard to read, he is actually quite a prankster with a sense of humor, telling jokes with a straight face or teasing those around him. This gap is especially apparent in his interactions with Ou Ki and Roku O Mi. 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 opponent sense his thoughts, he is a general whose movements are extremely difficult for enemies to predict. In short, Tou's greatest charm is the gap between being "usually detached and funny" and "overwhelmingly reliable on the battlefield."

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 adored 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 sense of admiration and inferiority toward generals with overwhelming talent like Ou Ki or Ren Pa. However, Mou Gou's true strength lies in his ability to spot talent he lacks and use it effectively. He is a Great General with an excellent eye for people, having managed to lead eccentric figures like Ou Sen and Kan Ki as his vice-generals.

A fierce general who prides himself on being the "strongest in China." He crushes enemies with overwhelming martial force and serves as the mainstay of the Ryo Fui faction, advancing through power rather than strategy. He is the son of Mou Gou and the father of Mou Ten and Mou Ki. He has a boisterous personality, trusting only in his own strength and disliking schemes or tricks, yet he also possesses the adaptability to change his tactics flexibly according to the war situation.

The father of Ou Hon and a subordinate of Mou Gou. He is a cold and extremely intelligent man who only fights battles he is certain to win. Age: Around 40s | Height: 195cm One of the Six Great Generals of Qin. He is a chilling individual who once harbored ambitions of becoming a "King" himself. Ou Sen is a genius general with such thorough caution and prudence that it is said he "only fights battles he can win." He is also very calm and skilled in social maneuvering; for instance, when requesting the military force needed for unification, he pretended to beg for rewards to lower the King's (the future First Emperor) guard and ensure his own safety.
