In a world where humanity was divided by tribes, there were children of the sun and the moon, each one had characteristics of their tribes.

There was a time when both tribes lived in harmony, until a son of the sun killed one of the moon, since then they have lived apart and at war if they met an opposing one they would kill him, so the sons of the moon only came out at night, then they hid, the same thing happened with those of the sun, they only came out when it was daytime. One night Xiao was born, a young man with bluish-green hair, although he was aware of the stories of his tribe that did not stop him from bringing out his brave and adventurous spirit.

It was daytime and his tribe was sleeping, he decided to leave the shelter and investigate what was outside when he was asleep. He walked aimlessly for a while, until he saw a boy his age and approached him from behind.

"You... are you a child of the sun?!"

Xiao asked in disbelief, his hair was very shiny!
