Naruto: An Ancestor Intervenes—Hashirama and Madara Are Comrades No More

[Naruto + No Female Lead + Brother Complexes + Female-Oriented, No Romance + System + Not a Power Fantasy + Quick Transmigration]

After his death, Indra watches his descendants and Asura's descendants fight endlessly. These unfilial brats actually let the Uchiha clan get wiped out.

The sole remaining Uchiha has a nearsighted daughter with a commoner woman. That daughter then marries a rebellious brat and has a child, and in the end...

The last Uchiha is gone!!!

His bloodline has vanished completely!

In his soul form, Indra loses consciousness in a fit of rage. A wish-granting system mistakes him for someone else, and when he opens his eyes again, he has been reborn as one of those unfilial descendants...

Then he keeps cycling through their bodies, completing missions.

Madara Uchiha's older brother... (Life isn't easy; Indra has to perform for a living.)

Sasuke on his journey of atonement... (Lay a finger on me, and I'll rip the top of your skull off.)

An elderly Madara Uchiha... (The countdown to death is ticking. I, Madara, demand immortality!)

Izuna Uchiha... (Hotheaded Izuna is online and losing his mind.)

Shisui Uchiha... (Blind Shisui steals eyes on the night of the massacre.)

Tajima Uchiha... (A son who starts dating too young deserves a beating.)

Sasuke Uchiha... (I'll help myself get sterilized.)

Itachi Uchiha... (Turning the family hierarchy upside down and smacking my own father.)

Obito Uchiha... (Crawling through the darkness.)
