Naruto: The Child Emperor, from Boruto: Naruto Next Generations to Shippuden

In Konoha Year 75, Sasuke Uchiha discovers a boy who poses a threat to the entire shinobi world while traveling through it. He destroys the boy’s laboratory and brings him back to Konoha.

At the strong recommendation of Konoha adviser Shikamaru Nara, the boy is imprisoned and placed under guard.

In Konoha Year 77, Takuya Yuki awakens the powers of the Second Child Emperor and escapes Konoha with the help of Ino Yamanaka.

While being pursued by Konoha, he uses a treasure to return to the past, twenty years earlier.

In Konoha Year 84, the Five Great Shinobi Villages have just defeated Ōtsutsuki Isshiki when they see a spacetime wormhole open in the sky, filling them with terror.

Beyond it stands an army of a hundred thousand from another shinobi world, led by the Child Emperor who fled Konoha seven years ago: Takuya Yuki!

“Konoha, are you ready to face the wrath of yours truly, Takuya Yuki?”
