Synopsis: Kengan Ashura

In Japan, it is customary for major business deals to be sealed with a fighter on the ground and another standing over them, a tradition that stems from the Edo period. This practice has persisted to this day, with the most significant companies settling their disputes through cutthroat gladiator battles. To facilitate these matches, the Kengan Association was formed and operates in secret. Ouma Tokita, known as "The Ashura," is resolute in becoming the most potent martial artist and signs up as a Kengan fighter for the Nogi Group. Kazou Yamashita is tasked with managing Ouma, despite his unremarkable job with the Nogi Group. Together, they must navigate the treacherous world of the Kengan arenas. Can they emerge victorious?
