|“||Now I understand why...Ri Boku-sama directed me to do battle at Rigan's side...It's because you give the same stench as me.||”|
—Kei Sha to Ki Sui
Ki Sui possesses a wore thinly mustache and beard. He has long brown hair slicked back and sports a white cape. On the battlefield he wears soldiers armor.
Ki Sui's overwhelming love for his hometown, Rigan inspires his soldiers to fight until the end. He is a kind ruler who cares deeply about his citizens and has a deep bond with his adoptive brothers.
Ki Sui grew up in the City of Rigan in the State of Zhao, which was at that time ruled by his father, Ki Shou, Together with Ba Tei and Ryuu Tou, whom Ki Shou fostered and raised together with Ki Sui, he would participate in the Battle of Tanko which was a war between Rigan and another city named Anka.
Although the battle was in favor of Anka due to them having twice the number of soldiers, Ki Sui managed to fight his way through an enemy unit numbering five times the amount of his men and slay the Lord of Anka, Tou Kan, securing Rigan's victory in the battle. The three of them were noted to be exemplary fighters by Ki Shou and his followers, helping to tip the scales of the battle back in Rigan's favor.
While he and his men were chasing the remnants of the Anka's army, Tou Kan's son, Tou Kin launched an attack on the City of Rigan itself, which was barely defended by heavily wounded soldiers from the war, Rigan eventually fell, and Tou Kin kept the women, children and elderly as a hostage. He then asked that Ki Shou and his followers give up their lives in exchange for the hostages to be returned alive. Ki Sui became agitated and furiously questions Ki Shou's followers as to why they were not stopping him, Later, Ki Shou and his followers were tied onto wooden poles and a fire was lit to burn them alive as the citizens of Rigan, including Ki Sui, watched on.
As the fire rages on, Ki Shou declares Ki Sui to be the next ruler of Rigan at the young age of 20 and asks that the citizens of Rigan give him their support. His last words were to Ki Sui, requesting that he kept "the children of Rigan safe". Ki Sui complied emotionally and determined, blood flowing out from his eyes in place of tears and under his lips.
Fifteen years have passed since the Tragedy of Rigan took place Ki Sui is now 35 years old and rules the city of Rigan in peace until the combined armies of Kan Ki and the Hi Shin Unit advance towards Kokuyou hills numbering 58,000 strong. Against this threat, Ri Boku sent his deputy Kei Sha along with 40,000 Zhao soldiers to help reinforce the area together with Rigans 30,000 troops. During the Battle of Koku You Hill, he is shown inspiring his soldier just by appearing allowing them to fight with double the strength than before.
In the battle of Koku You Hill, both sides have seen fierce fighting, vying control over the largest hill for Strategic defensive point. In midst of the battlefield, Kei Sha, annoyed by Kan Ki's decision to hold his army from attacking, led his personal troops in an attempt to destroy Hi Shin Unit completely, only to fall into Kan Ki's trap device by being cornered by Zenou Clan. Ki Sui went to saved Kei Sha who was surrounded by Zenou Clan and hold them at bay. Though Successful, Kei Sha was slain by Shin, and the Rigan army were losing ground with the absence of Ki Sui and his two brothers. Furthermore his brother Ryuu Tou was slain when he attempted to stop the Hi Shin Unit from reaching Kei Sha.
When Ki Sui was called to hear the news of the death of Kei Sha, he persuaded Kei Sha's closest subordinate to aid him the battle while keeping a secret of Kei Sha's death for fear of losing morale. With the death of his brother, Ki Sui and Ba Tei were enraged and fought fiercely, which turns into a stalemate for both sides. To Ki Sui's surprise, Kan Ki ordered a withdrawal from Hill and allowed Zhao to set up a defensive perimeter around the central Hill. Confused, Ki Sui begin to worry what sort of tricks that Kan Ki has.
A day after Qin's withdrawal from the Hill, Ki Sui was invited to see Kan Ki's act of cruelty upon the victims that lived near the hills, as a sign of 'Gifts' to Ki Sui's bravery while Kan Ki threaten that he will do more on Ki Sui's homeplace. The fear of Kan Ki's Cruelty, led Ki Sui to have the whole Rigan's army to withdraw the battlefield despite Kin Mou plea to stay behind, as half of Kan Ki's army moved to aim at Ki Sui's home. Ki Sui and his men chased down any stragglers along the way and reach to their home. Ordering his people to evacuate as it is no longer safe when Kan Ki's around.
He and his army was attached with the Ri Boku Army when defending Atsuyo from Ou Sen and Qin Armies. As Zhao's Right Wing commander, he initially faced Mou Ten army that prepared the stage for Ma Kou army's wave attack. He was pursued by a killing stroke detachment consisted of 800-unit soldiers lead by Shin , but was saved by the assassin-like attack of Ri Boku to Qin's Left Wing commander Ma Kou. With the death of Ma Kou and advisors, Qin's Left wing army were leaderless and this turned the table around. Taking this advantage, Kisui ordered his army to push and eliminate the Left Wing Qin Army, only to had the battlefield turn into a Stalemate with the intervention of Shin and Mou Ten. And Mou Ten being posted to lead the Qin's Left Wing army.
The rest of the of the battlefield on Left Wing Qin Army Vs Right Wing Zhao Army would under a stalemate until Zhao's central army were threaten by the pincered attack of Qin's Central army and Left Wing Qin Army. Ki Sui sent Ba Tei to aid the Central Army, later on aided the central Army to withdraw.
With the Zhao's complete withdrawal, Ki Sui's army joined up with the central army to head to Gyou in the attempt to lift up the siege. But was pursued by Qin's Strong Cavalries of 2/10 of their whole army. Ki Sui and his army was forced to hold position and fight against the pursuers before taking heavy casualties and allow Ri Boku's army to pass through before Gyou has been taken.
In the end, Gyou falls to Qin. Ki Sui and rest of the Zhao's army guided the Refugees to safety.

Ki Sui possesses an impressive martial skill and is capable of fighting with both glaive and sword on the battlefield. During the Battle of Tanko, he was able to fight his way through an enemy that numbered five times as many as his men, and personally killed the enemy lord, Tou Kan. He easily slain Kaku'Un with a single strike. Ki Sui was even able to block a heavy hit from Zen Ou, although it bended his glaive.
Ki Sui's gratest talent seem to be his leadership abilities. During the Battle of Koku You Hill, he demonstrated great bravery as well as rallying abilities when he saved Kei Sha from Kan Ki's trap. According to Koku'Ou, he has the ability to inspire his troops to fight twice as hard by just showing up on the frontlines. This was demonstrated when he easily pushed back Koku Ou forces.
Ki Sui's Rigan soldiers are also considered one of the best in the entire Zhao Military. His elite cavalry unit was said to hone themselves to the utmost peak from their training and is able to ride down difficult terrain like vertical cliffs to strike the enemy.
Ki Sui is a capable strategist and tactician that showed quick wits and good decision-making skills. When Kei Sha fell into Kan Ki's trap he felt something was off even before Zenou's counterattack, demonstrating sharp intuition. After Kei Sha's and Ryuu Tou's death, he created his own plan for the overall battlefield that enabled Zhao to once again push back Qin forces and gain upper hand.
