Gion, the King of Reason, is a warlord once allied with the King of Fist’s army. He commands a military expedition to the Valley of the Black King, determined to secure the prized wild horses inhabiting the region. The campaign ends in catastrophe as the herd decimates nearly his entire invasion force, leaving staggering casualties in its wake.

After the debacle, Raoh confronts the horses and tames their leader, the Black King. Compelled by Raoh’s overwhelming might and the futility of defiance, Gion surrenders. Despite his defeat, Raoh spares him, integrating the strategist into his own ranks as a general to harness his tactical acumen. Before yielding, Gion is gripped by dread upon learning of Raoh’s advance toward his fortress—a stark revelation of his vulnerability against an unstoppable force.
