Naruto's Nine-Tailed Fox Cousin

On the night of the Nine-Tails' attack, Uzumaki En transmigrates to the world of Naruto and saves Minato and Kushina. Bearing the power of the Nine-Tails, he becomes Naruto's cousin, the Nine-Tails' other jinchuriki. With his parents there to raise him, Naruto grows up surrounded by love.

The Uchiha clan is no longer pushed aside by Konoha's leadership. Itachi becomes part of Minato's faction, no longer weighed down by hatred, and can finally look after his foolish little brother in peace.

The name Shisui of the Body Flicker resounds throughout the ninja world. But why does his Body Flicker Technique look a little like the Yellow Flash's?

Having put his past behind him, Kakashi is still the peerless genius who became a jonin at just twelve and developed the Chidori!

The masked man Obito Uchiha, who has been using the name Madara Uchiha, can no longer hide his true identity.

Minato: Obito, you're still alive? I once hoped you would become Hokage.

Naruto: You're the bad guy who attacked my mom and the village on the day I was born. So, prepare to die.

Uzumaki En nodded with satisfaction. “As expected of the good kid I taught myself!”

Uzumaki En: With the power of all the tailed beasts gathered within me, I am the Sage!
