Hero Overview

Ton, Tan, Tan...
~ Kyou Kai's Signature Dancing Chant.
O ancient darkness...primordial flame, what is it that lies...within your eyes? O bright light that splits the Heavens, rumbling tremors that shake the Earth, what pulse beats...withing your ears? Man walks adrift, a vessel of the Earth. I dance for thee, O God of Lightning! Ah...Ryoku Sui...Let blood boil over!
~ Kyou Kai's Dance Pray as she readies herself to fight Hou Ken, Kingdom v57.

Kyou Kai is a deuteragonist and tritagonist of the popular historical seinen manga and anime series, Kingdom. She serves as the second lieutenant of the Hi Shin Army and a 5000-man commander of the Qin military, and was a former assassin from the infamous Clan Shiyuu. She is one of the strongest combatants and most versatile fighters within the army besides Shin (being far stronger than him) and is also one of the smartest tacticians alongside So Sui and Ka Ryo Ten during the Warring States era of ancient B.C. China.

Introduced as a mysterious Qin foot soldier during the Keiyou Campaign Arc, Kyou Kai ended up joining a 5-man squad or "leftovers" with Shin, the Bi Brothers - Bi Hei & Bi Tou led by Taku Kei, a veteran infantry soldier as they fought in the Battle of Dakan Plains as a part of the Duke Hyou Army. She later reappeared as an antagonist of the Assassination Plot Arc against the Ei Sei Faction under orders from Ryo Fui to kill Ei Sei, the king of Qin until circumstances forced her to team up with Shin. Towards the end of the arc, it was revealed that Kyou Kai was a female warrior and needed information on the whereabouts of the Shiyuu, Yuu Ren who was responsible for killing her beloved adoptive older sister Kyou Shou with underhanded tactics during the succession ritual of Clan Shiyuu. After meeting Shin and finding ''another place to return to'' Kyou Kai became a lieutenant in the fledgling and newly formed Hi Shin Unit during their early days as a 100-man unit.


Kyou Kai was a relatively short and petite girl with large jade green eyes with shoulder-length hair tied into a ponytail with a ribbon in her early appearances. Two strands hair fall on each side of her face with her bangs reaching eye level whenever she takes her headband off and carries her exquisitely beautiful jade green and ruby embodied Chinese Jian sword known as Ryoku Sui on her back. By the end of the 2-year time skip after Qin's victory over the Coalition Army and returning to the Hi Shin Unit after getting vengeance for her sister's death, her hairstyle subtle change with two thick strands of hair overlapping her headband and her becoming even more beautiful. In terms of clothing, Kyou Kai wears a white scarf and dons red and white clothing with sleeves longer than her arms and a white headband with two red markings symbols of her tribe.


Kyou Kai is quiet individual, sometimes says very little or nothing unless she is giving out tactical advice to either Shin or Ka Ryo Ten. While showing little care for them, Kyou Kai holds disdain for those who are clueless about her clan. As a trained assassin, Kyou Kai will not hesitate to kill anyone who gets in her way. Others who have seen her inhuman talent with the sword have called her a "monster" as she cuts down her opponents with ease. Since accomplishing her quest of vengeance, she has grown warmer towards her comrades as they find her more approachable now.



You guys, run away immediately!! I cannot lose this place.
~ Kyou Kai telling the Hi Shin Unit to run.
...Y'know, you really are cute after all. Especially when you're smiling.
~ Shin to Kyou Kai

Fighting Style
