In the 30th year of the Fire Yuan, the Kingdom of Fire became the first of the five great kingdoms, built a royal city, and established a spiritual king.
In the eighty year of Fire Gen, the fourth Soul King was succeeded by Namikaze Minato. In the same year, Uzumaki Kushina, the princess of the Sealed Kingdom, became the queen, and Uchiha rose as a military commander.
Since then, there has been no major war, and the royal city is thriving.
After the border war, Uchiha was made a general. The following year, both the queen and the general's wife were pregnant.
