Sadao Kageyama

Sadao Kageyama is a Human male with grey hair, grey eyes, and a lean build. Born in a different continent separate from Enith, Kageyama desires one thing: to venture from his homeland and learn all there is to be known. Being a Holder of the Chikara, Stiletto, allows Kageyama to manipulate any sharp object around him, giving him close and long range advantages.

Kageyama is the only Human in history to have learned Primal Release, being one of the first people to make contact with the Nekoken jungle tribes and be made kin.

Origin
Kageyama's family originates from Enith but moved to Dalu with a large group of travelers. When Kageyama was born, they informed him of their transition, which causes his departure back to Enith to learn of his native continent.

Shimetsukeru Arc
After the journey back from Shimetsukeru, a man is found meditating outside the Temple of Hope's main building, prompting Isui to question him. Kageyama ignores Isui's question and resumes meditating, angering Isui. However, just before Isui could do anything, Sayuri intervenes and explains: "Mr. Sadao is from a faraway land and wants to learn from this country's hero (speaking of Kazega Eijizoyo)." Isui looks around, confused, and Kageyama suddenly stands up to interrupt. Kageyama soon finds out that Kazega is unconscious due to both his injuries and overuse of his Chikara.
