On a continent called "Kan Aitia", various major biological races live here. They followed the laws of nature, established a country, and coexisted harmoniously.
But behind the peace, there is a cruel battle with bloody killings.
Every hundred years, the legendary "Lord of the Rings" will appear in the world. The "Lord of the Rings" has the ability to grant any wish, and any wish can come true!
Under this temptation, all countries and forces have reached an agreement that no foreign action is allowed except under special circumstances. A duel will only take place when the "Lord of the Rings" appears - the winner gets the "Lord of the Rings" and the loser dies!
All living beings know the horror of the "Lord of the Rings", so on the day it was born, the entire continent changed, and all forces gathered in Kanaitia.
