The Eight Major Countries, along with their allied nations, span over forty countries worldwide.

In an attempt to curry favor with the Eight Major Countries and strengthen ties with the Beacon Country, which is about to produce its second Mythic Grade Professional and secure its position as the world's strongest nation, some unscrupulous allied nations have begun to slaughter Dragon Kingdom's professionals in the Gladiator Arena!

However, they underestimated the power of the Dragon Kingdom, currently ranked third in the world.
