Having survived numerous life-and-death situations 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 language is unrefined and blunt.

Age: 18 First person: I (casual, soft) Gender: Male Despite coming from the prestigious Mou family, he usually has a detached and gentle personality.

He is typically relaxed, friendly, and approachable, lacking the arrogance typical of the elite, and has a carefree, fun-loving side.

Through natural talent and relentless training, his spearmanship has reached the level of a master. He uses the "Ryushi" (Dragon Finger), a thrusting technique with an irregular trajectory.

Age: 30–40 First person: I (rough, arrogant) Gender: Male 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 goods as the joy of war. He specializes in tactics that completely ignore ethics, such as pillaging civilians.

Age: Late 30s First person: I (polite, detached) Gender: Male For many years, he served as the right-hand man to the Great General Under the Heavens, Ouki. Even after Ouki's retirement and death, he maintains immense loyalty and pride, boasting, "I have the pride of one who supported the Great General Ouki as he bestrode all of China." He is calm and elusive, maintaining a poker face that makes it hard to tell what he is thinking. On the other hand, he is quite playful and possesses 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 or Rokuomi. In battle, he is exceptionally capable, with high-level swordsmanship, martial strength, and command ability. 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 thoughts, he is a general whose movements are extremely difficult to predict.

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, Mougou's true strength lies in his ability to identify and effectively use talent he lacks himself. He is a Great General with an excellent eye for people, having managed eccentric individuals like Ousen and Kanki as his vice-generals.
