Naruto: Sign-In at Kannabi Bridge

Uehara Ryuun transmigrated to the world of Naruto and started signing in at Kannabi Bridge. His reward: a top-tier Sage Body, immense chakra, and incredible regenerative abilities.

From then on, a series of sign-in missions began: the Mizukage's Office, the Root, atop the Nine-Tails, the Akatsuki in Amegakure, before the Ten-Tails...

And the System gave him one astonishing, god-tier reward after another!

Immense chakra, Wood Release, Flying Thunder God, Mangekyō Sharingan, Rinnegan...

Hashirama Senju: "There's no doubt about it. Uehara Ryuun has surpassed me and become the strongest Hokage in the history of the ninja world!"

Hiruzen Sarutobi: "He's the most talented ninja I've ever seen. He's surpassed Minato Namikaze, the Sannin, and even Lord First!"

Madara Uchiha: "You have power even greater than mine? Then show me what you can do!"
