The saga of the Slave King tells the story of a young princess king who ruled the land of Nistaburi with justice and wisdom.

It is said that in ancient times, in the land of Nistaburi, there was a wealthy merchant with seven sons and daughters.
His eldest son was a girl, and his name was Sifat Akal; the second was a boy named Sifat Bicara, then Sifat Soal, Sifat Jawab, Sifat Cahaya, Sifat Budiman and Sifat Iman.

The slave king was named Sifat Akal, who, because of his intelligence and wisdom, although still a child, had been appointed princess king by the court officials.

Because Sifat Akal was still a child, young in age, he called himself the Slave King, while his six younger siblings were made his prominent servants.

As children, the seven sons of the merchant have shown their intelligence in politics, Islam, morals and character.
