Kanayama Jou AKA King Joe is the King who ruled Housen with an iron fist for years. Considered the greatest man in Housen's history, he took control of the school in his first year. He was known for ending the Bitou dynasty at Housen.
One of The Four Kings in his generation,which according to Fujishiro Takumi, Joe is the most terrifying even among them. A testament to this is when as a first year he almost beat the Kurotaki Alliances president Osamu Furukawa but was countered at the last minute. As a freshmen Joe was very ambitious, and always looked for a good fight, of The four kings he only has a single one on one with Takeda Kousei, though the winner of the fight is never revealed.
In the twilight of his reign as Housen's leader, the Moonlight Brothers pushed Joe to start a war with Suzuran. He complied, despite knowing that Housen would completely lose against the School of Crows. Joe proved to be quite the strategist and did everything in his power to make sure Housen defeated Suzuran, elaborately ambushing three of their key leaders, including Zetton, which he supervised personally.
Joe took advantage of the war to pass the reigns of Housen's leadership onto Mitsumasa Tsukimoto, who was forced to sit out the one-on-one matches. By forcing the younger Moonlight Brother to not participate in the matches, Joe taught him a vital lesson in the ways of leadership. Joe was also the only Housen member who won his one-on-one match against Katou Hideyoshi in the war against Suzuran.
Kanayama moved to Housen from Okayama. In his freshmen year, King Joe began making a name for himself among the freshmen year. Tsukimoto Mitsunobu, who was favorite to rule the freshmen class and inherit the leadership from Hideyuki Bitou, heard rumours of King Joe and decided to challenge him. When Tsukimoto and six of his followers confront him, King Joe states that if he beats Tsukimoto and his six followers, he will be the top of the freshmen class. King Joe took out a frying pan and began beating them, stating that in a 6 vs 1, this was his handicap. After beating Tsukimoto, King Joe stood above the freshmen class. King Joe participated in the trip to provide back up for Tatsuya and the P.A.D against the Snakehead gang.
Towards the end of the year, King Joe called out Tatsuya to the roof top of Housen. King Joe asks him that he isn't the leader of Housen, but that his brother Hideyuki is the leader. When Tatsuya asks him what of it, King Joe proceeds to ask what would happen if he defeats Hideyuki. Tatsuya replies that he would then be Housen's leader. King Joe tells him that he is glad it is that simple, to which Tatsuya asks for his name and that King Joe states he was pleased to meet Tatsuya.
In his sophmore year, King Joe established himself as one of the Town's Four Powers (The Big Four). Hanazawa Saburou, Takeda Kousei, Nakajima Shinsuke and himself kept the peace in the city. After an incident where eight Housen soldiers and Housen's number 2, Ujiie Jun were beaten by a Suzuran freshmen, King Joe invites Hanazawa to meet him and warns him to approach the situation carefully, stating that if the balance at Suzuran is disturbed, then the balance in the entire town will be disturbed. When word got out that Hanazawa lost to Hanaki Guriko, King Joe states that he was an idiot.
