They were born into the world with only chaos and death to greet them. For on that exact day, their parents and many others had died. 

A great burden was then passed unto them: To Naruto, the beast that had tried to destroy the village was sealed unto him; and to Minashi, the instinctive obligation to be dragged down in whatever Naruto does.

But as time passed, they became the Yin and Yang of Konoha, a powerful pair that excels in each of their skills and are even more powerful when chakra fusing. They became known as the Lethal Duo.
