A generation that has been cursed for 500 years.

The family-line can only bore one son, and the father must sacrifice himself to search for the Gem of Forgiveness in the hidden mirage.

If this sacrifice is not attempted, the entire family will perish.

Nothing can stop this curse. And the past five generations of fathers who were summoned to save their sons by combatting this curse created by their ancestor have died in the mirage for reasons unknown.

Only son and mother remains.

But now.

Kai must take his father's place to seek the mysterious Sapphire Gem.

Will the curse kill him and eventually end the Kim family line? 

The mirage appears once every one hundred years. No one knows where it will appear this year.
