When Upper Moon One is Reincarnated as an Uchiha

[Synopsis] The main story is complete, and the extra chapters are wonderfully under construction. 50% anti-theft, thank you for supporting the official version vv

Michikatsu is well aware that a blood-soaked demon like himself will undoubtedly fall into hell after death, never to be reborn—if hell truly exists in the world.

But when he opens his eyes again, he is reincarnated as a newborn baby.

In this life, his name is still Michikatsu, but his surname has changed; his full name is Uchiha Michikatsu. He is still born into a prestigious family, but one renowned in the ninja world.

The world he is reincarnated into is incredibly magical. People can breathe fire and water, move mountains and fill seas, and even control people's minds with a single glance. His family, for instance.

Oh, by the way. Perhaps due to the countless sins of his past life, his body in this life is extremely poor, and coughing up blood is a daily occurrence.

In everyone's eyes:

Uchiha Michikatsu was born frail and was on the verge of death eight times just after birth. Such a weak child, let alone going to the battlefield, it's questionable whether he can even survive.

But just such a sickly person, despite coughing up blood every day, managed to pull through.

However, this is probably all he will amount to in this life.

Until one day, the sickly person that no one was optimistic about transforms and is crowned king—under the heavens, there is no land that is not the king's land; leading the shores of the earth, there are no subjects who are not the king's subjects.

The Five Great Nations? From this day forward, there is only one nation.

Before everyone could recover from this reality that was more absurd than a dream, he, while coughing up blood, swung his sword, and with just one strike: the mountains split, and the sea tide rolled back.

The entire scene fell silent.

...

Many years later, the history books recorded:

"Uchiha Michikatsu, who unified the chaotic world and created an era of peace... never married and had no children."

"His three generals—Uchiha Masaki, Uchiha Uta, and Senju Yoriichi. With the exception of Uchiha Masaki, the latter two also never married and dedicated their entire lives and loyalty to Lord Michikatsu, and their respective great causes without reservation."
