Plot
Part 1
In the final round of the Battle Arena Toshinden tournament, Eiji Shinjo faces the tournament's sponsor, Gaia, in a final duel. Gaia mentions that Eiji's skills are comparable to those of his long-lost brother, Sho, but before he can explain, the fight is interrupted by a man called Chaos, who works for the same Organization as Gaia and has been sent to eliminate him upon discovering that Gaia is rallying fighters to overthrow the Organization. Gaia slays Chaos and flees, leaving the tournament without a winner.
A year later, both Sho and Chaos, the latter having apparently survived his fight with Gaia, working for the Organization's leader, Lady Uranus, begin hunting down the fighters from the tournament, such as Fo Fai, Rungo Iron and Mondo. Eiji, along with his best friend Kayin Amoh, split up to warn the other competitors.
