The mystical realm where the Olympic Games are being held was a great terrain created by the Saint Mages of the International Magic Olympic Committee together with the Empire of Japan's Saint Mage.
The size of the kingdom was equal to the Empire of Japan's half territory, the location was extremely large. Participants had a month to explore the site and complete missions.
To improve competition among participants, the kingdom had many rare natural treasures for cultivation. Participants were free to pick up these items to use or sell later.
Just as there are rare treasures, there are also powerful creatures protecting these treasures. The creatures' powers limit was that of a Warrior Mage, as there were participants with this level of power. That was the limit for young people up to twenty-five years old.
