Naruto: Starting from the Reincarnation of the Otsutsuki.

As a transmigrator who has lived two lifetimes in the ninja world, Hyuga Seiran has witnessed too many bloodsheds in the name of peace.
When the Otsutsuki chakra manifested within his body, Hyuga Aoran silently made a decision.
"Since this tree called Ninja is completely rotten, I will uproot it."
-----------
When the "Otsutsuki Aoshiki" in the dusty scroll, the savior "Hyuga Aoran" praised by the world, and the "Ao" hidden behind the scenes who makes the Five Kage tremble day and night...
The three identities were stripped of their disguises before the world, merging into one.
All hope in the ninja world was shattered at this moment.
"I'll say it again, the ninja era is coming to an end."
Hyuga Seiran, high above the heavens, looked down upon the trembling Allied Shinobi Forces below, who resembled ants, and calmly said:
"From this moment on, chakra returns to its origin..."
"The ninja system is hereby abolished."
