Houkou Kakuka, also known as Kakuka Houkou, is a male student from Kyoshou Gakuin and the successor to the historical figure Guo Jia. Born on September 1st under the Virgo sign, he stands 174 cm tall with blood type A and holds an A-Rank fighter classification. His appearance features spiky brown hair that later turns gold. Kakuka initially wears the standard Kyoshou uniform—a black coat over black pants and a red shirt—later shifting to a white button-up shirt with blue pants. Kakuka wields a seductive and manipulative personality, particularly attracting women, and makes Bunwa Kaku his lover. He demonstrates ruthlessness by willingly sacrificing his best friend Genjou Kakouton's eye to awaken Moutoku Sousou's dragon power, though he later expresses deep remorse for this act. Kakuka maintains a close friendship with Sousou and Kakouton. Destined to die young from cancer but cured, his health condition causes him to appear ghostly around Kaku. In the manga, his story culminates in an attack by Youjou Bashoku, who frames Kouha Kannei, leaving Kakuka in a coma. In the anime *Dragon Destiny*, Kakuka plays a more active strategic role, deliberately awakening Sousou's dragon to further Kyoshou's conquest of Kanto while grappling with guilt over Kakouton's injury. His strength is pronounced, defeating Shimei Ryomou easily in the first season. An assassin, later revealed as Bashoku, ambushes him. Kakuka anticipates the attack due to his foretold early death but is poisoned during the struggle. He succumbs to his wounds on the street after urging Kaku to seek out Myousai Kakouen. Kakuka's relationships are central. He shares intimate moments with Kaku, who is deeply affected by his death. His bond with Sousou and Kakouton underscores themes of loyalty and betrayal through his sacrificial actions and regret.
