|Shou Bun Kun Army|
|Name||Shou Bun Kun Army|
|Affiliation||Ei Sei faction; Qin Military|
|General||Shou Bun Kun|
Before Shou Bun Kun became an official in the royal court, he had been a war officer for many years building his military career alongside Ouki who was his old friend and they fought with each other for years. He has his own land and his own army which he used to protect Ei Sei, when no one else was helping.
When rumors about an assassination attempt on the king rose, Shō Bun Kun came up with the idea of using a body double to distract the pursuers, while Ei Sei would escape in a secret fort hidden in the mountains. The army escorted Hyō, the body double, when they got attacked by general Ouki. Despite getting defeated, the army somehow survived and managed to reunite with their king.
Together, and joined by the Mountain Tribes, they attacked Qin's royal capital and defeated the rebels, returning the throne to its rightful owner. After that, Shōbunkun became the king's adviser, so by default his army remained inactive. It is unknown, however, if the army was disbanded or not.
Heki is his loyal retainer and lieutenant, a ,then, 1000-man commander in the military who later earned promotion to a 3000-man commander. After Ei Sei took back the throne, they decided that it was best for Heki to take over Shobunkun's place and advance on his way to become a general.
Shou Bu Kun Army used to be an independent unit that was entrusted with special missions.
