Story
Long ago, there was a conflict between the forces of light and shadow.
It's said that the war was subdued by 7 warriors of light, and the forces of shadow were all sealed in one place.

This is the legend of the warriors who saved the world.
It is just one part of the story written in the oldest book in the world, called the 'Book of Beginning'.
Though they were called warriors of light, they had the ability of shadow, and even after their deaths their abilities were inherited by others, yet never surfaced.
But now, with the awakening of shadow abilities in Zola and Nene, the world is about to be thrown into chaos once again.

Nene, ruler of the Gran Kingdom, is setting out to use the power of shadow for world domination.
In order to save the world from this ambition, Zola sets out on a journey to find the descendants of the 7 warriors of light killed in battle.
The actions of these two involve Shu and Kluke, who live in the peaceful Talta Village.
When Zola appears in the village with Jiro, who is one of the descendants of the dead warriors, Nene's army attacks them there.
During the battle, Shu invokes a shadow called the Blue Dragon, and begins travelling with Zola.
