After the atomic war in 2025, only a few parts of the world were liveable.
About 2.5 million humans survived by seeking shelter, hiding underground.
It is now 2196, but nothing has been rebuild, there are still a few buildings and historic monuments that survived the war.
There is barely any food or water, no electricity, and that's all because of the war between the 6 kingdoms for power over the liveable land.
In the year 2057, a profecy was found, saying:
"as all hope is lost, a child shall stop the wars, a child with a pure soul, they will have trouble on their path, as well as death and love."
Later, another profecy was found, but was never released to the public, saying:
"The saviors name will be Akio, they will have brown hair and Topaz eyes for the Topaz kingdom, winning from the Silver, Diamond, Golden, Emerald, Ruby and Opal kingdom" and in 2189, that child was born.
