For one year, Master Swordsman Eiji Shinjo has been haunted by the memory of his battle with the renegade champion, Gaia - a battle that was cut short by the forces of the malevolent syndicate known as "the organization."
Denied victory, Eiji left the tournament followed by his opponents mocking laughter. Worse still, Eiji walked away no closer to finding his long lost brother, Sho.
