The red dragon god took on human form, descending from heaven to rule a kingdom on Earth. He was the first King of Kouka, King Hiryuu. But once King Hiryuu became human, he eventually had to fight humans. The people's hearts filled with evil, they forgot their god, and their country fell to ruin. Even King Hiryuu was captured by humans who desired power. Just when everything seemed on the brink of destruction, five dragons descended from heaven.
"Hiryuu, we have come for you. Let us destroy the humans, who have forgotten their faith, and return to heaven!"
Hiryuu rejected them, "No, I am human now. Though the humans may hate and betray me, I cannot help but love them."
The dragons loved Hiryuu, as well, and did not wish to lose him. In order to protect Hiryuu, they gave their blood to human warriors, and granted them strength. One gained sharp claws that could tear apart anything. One gained eyes that could see across great distances. One gained a mouth that could spit the hottest fire. One gained legs that could jump high into the sky. One gained a strong body that could never be injured.
"You are now our other halves. You will serve Hiryuu as your master, protecting him with your lives. You will love him, and never betray him."
With the power of the dragon gods, the warriors led their clans to protect Hiryuu, and brought order to the kingdom. Before long, the red dragon grew tired of fighting, and fell asleep. The mission of the five dragons thus ended. They thought of their king, no longer moving, and wept. They did not know whether they grieved the loss of someone precious, or if the dragon god blood within them mourned Hiryuu's death. Realizing their power was beyond human control, the five dragon warriors left their tribes and disappeared. The tribes they left behind continued developing on their own, forming the six tribes of today.
