Kentei

As the primary antagonist, this character masterminded a scheme to conquer the Kanto region by manipulating the leaders of Nanban High into a fake tournament on Nanban Island, using assassins to eliminate defenses and resurrecting vengeful spirits through the blood of the fighters. Driven by intense ambition, hatred, and a desire for chaos, this being embodies the vengeful spirit of historical figures, including the essence of Guan Yu's rage, aiming for total anarchy. Despite his dark machinations, he harbors a fear of those who control destiny, particularly Hakufu, and has a complex relationship with another force striving to alter fate.
