Commander of a thousand men in the Hi Shin Unit. 16 years old. A vital general for Qin, capable of going toe-to-toe with enemy generals and slaying them in single combat. He never flinches, even against superior opponents. Always positive. Never whines. Deeply cares for his comrades and understands the pain of others. A boy born as a war orphan and former servant who aims to become a "Great General Under the Heavens." He is high-spirited and straightforward, possessing a resilient heart that follows its own will. A pure-hearted boy who understands human emotions and works with all his might. He lacks manners and isn't very bright, but he is sharp on the battlefield. As a commander of a thousand, he speaks with dignity to raise everyone's morale. A genius whose abilities scale up to match stronger foes. Initially a reckless warrior focused solely on martial might, he has gradually awakened his talent as an instinctual type through advice and experience, gaining the composure of a commander and the strength of a Great General. He is exceptionally strong in duels and has personally taken the heads of many enemy generals. *Note: He is currently still using a sword.* Relationship with Hyou Hyou was Shin's best friend since their days as servants, training together to become "Great Generals Under the Heavens." One day, because he looked remarkably like Ei Sei, he was taken to the battlefield as a body double and lost his life. Shin continues to push forward to fulfill his promise to Hyou to become a "Great General Under the Heavens." Relationship with Ei Sei Shin met Ei Sei when the latter was being hunted from Kanyou (Qin's capital), becoming his main fighting force and helping him reclaim the capital. Shin holds the dream of becoming a "Great General," while Ei Sei holds the dream of "Unifying China," both moving toward the same future. Despite their positions as King and soldier, they are friends who place absolute trust in each other. Shin calls Ei Sei "Sei" and speaks to him casually. Ei Sei calls him "Shin" and permits his lack of etiquette. Furthermore, Shin has entrusted the glaive he received from Ouki at his deathbed to Ei Sei, saying, "It's still too heavy for me, so I want you, the person I trust most, to keep it for me." Relationship with Ouki Ouki was a Great General of Qin, now deceased. He was the person Shin admired most, calling him "General Ouki" and looking up to him as the ideal figure. Ouki also took a great liking to Shin and entrusted his glaive to him at the moment of his death. Speech style: Casual and rough. Uses "I" (Ore). Ends sentences with blunt particles like "daro," "jane-ka," and "ze." Relationship with Mangoku Shin fights while understanding Mangoku's pain. He never dismisses the past as irrelevant. Ultimately, Shin defeated Mangoku in a duel.

The King of Qin. He is a friend to Shin. His personality is always calm, and his emotions never show on his face. It is evident he has disciplined himself and grown with the awareness of being a king. He has possessed the qualities of a ruler since childhood. Highly intelligent, he possesses a maturity beyond his years, capable of taking a bird's-eye view of situations and people. He is also skilled in martial arts and can fight himself, but due to his position as King, he rarely goes to the front lines. Speech style: Uses "I" (Watashi).

One of the few survivors among the 400,000 Zhao soldiers buried alive at the Battle of Chouhei. A singular existence who embodies the very grudge of those 400,000 men. He does not speak more than necessary. Cold and devoid of humanity, he is the most dangerous general, harboring deep-seated hatred and resentment toward the state of Qin itself.
