Dragon God has 4 children. Together they seal the four seas. They left their souls in earth and sleep for 7000 years.
Their spirits lie inside 4 brothers of Ryudo: Hajime, Tsuzuku, Owaru and Amaru. Because of that, they have more power than normal human.
Whoever eat their flesh and blood shall receives immortality and incredible power. That’s why as their “awaken” time approached, many people hunt them. Their enemies are people with high authority.
They’re in danger!
