Kan Jou wears armor along with bracers, He has a goatee and a mustache, and long dark hair that is tied, He usually looks very calm.
Kan Jou is a clever man, carrying a mysterious presence with him. He has proven to be an analytic and careful warrior, who is able to raise skilled and powerful soldiers. Sometimes he acts on his own whims, in order to ensure success, even if it means to deny orders of his young lord Ou Hon.
Kan Jou seen as a commander of Wei back in chapter 366 being captured by Ou Sen within Keito city. Sometime after swearing loyality to Ou Sen he was assigned to be apart of the A Kou Army. Until Ou Sen reassigned him to the Gyoku Hou Unit half a year before the Chiyoyou Campaign.
During the Chiyoyou Campaign, he was assigned commander of the Gyoku Hou's right wing. On the second day, he was able to clear out the enemies in the southern forest in a short amount of time. Later on when the Shi Haku was attacking the Gyoku Hou's centre, Kan Jou circled around to attack their rear.
During the skirmish, Kan Jou noticed more troops from Wei's additional reserves were moving to cut off the Gyoku Hou's path of retreat and ordered all the troops to halt. At their meeting, Kan Jou explained that whether it was the war chariot's sudden attack or the charge mounted by the cavalry, all of it was done as to keep them occupied there. By getting worked up and reacting to their attack as they did, they played right into the Wei's hand. Ou Hon stated that the enemy's defensive line should had been further in. Kan Jou explained that it meant the enemy chose to ride out and meet them there. Kan Jou then told Ou Hon it was still possible for them to avoid the encirclement. So he proposed Ou Hon order the men to disengage and sound the retreat. Ou Hon refused, saying they would proceed onward and take the enemy's commander's head. Ou Hon explained that the defensive formations which protected the enemy's rear had been pushed aside to the left and right, and if they assumed a wedge formation and charged into their ranks, it would be possible for them to reach the enemy commander. From there, all Ou Hon needed to do was slay him within three thrusts and they should still have plenty of time to escape the encirclement. Kan Jou thought Ou Hon's plan was impossible. He explained that going too far in to clash with the enemy would make disengaging extremely difficult. Not to mention, they had no guarantee that Ou Hon would be able to slay him in such a short time span. Seeing as it was far too large of a gamble, Kan Jou advised Ou Hon to pull out immediately. Ou Hon, frustrated with arguing, ignored Kan Jou and proceeded with his plan. As he was about to charge the enemy, Kan Jou told him that Ou Sen would never attempt something so risky. Ou Hon asked his point? Kan Jou told him he was being too reckless with his life, and as the next in line to the Ou Family he should be more prudent with his decisions. Ou Hon replied, stating that the battlefield wasn't a place for personal sentiments such as those. And in any case, his decision had taken into account how much time they had to spare, as well as the strength of their cavalry. Ou Hon then went on to tell him to rest assured, that he wasn't being reckless, and he should not make light of the Gyoku Hou's strength. Kan Jou told Ou Hon that the right wing would not be able to accompany him, to which Ou Hon replied by telling him to do as he liked, then proceeded to make a charge for the enemy. Kan Jou was asked by one of his subordinates if his decision was okay, to which Kan Jou replied that it wasn't, as if Ou Sen sent him to the Gyoku Hou to safeguard Ou Hon. Ou Hon then reflected on his earlier statement and had his men disengage.
