Naruto: I Have a Gravity Training Room

Natsuki arrived in the world of Naruto and chose to abandon his savior complex, leave the saviors to their destinies, and live only for himself.

Naruto: "Sasukeee!"

Sasuke: "Narutooo!"

Sakura: "Stop it, you two! Stop fighting!"

The rain kept pouring, coming down in torrents. Natsuki sat off to the side munching on sunflower seeds, sharing a handful with his girlfriend, Tenten.

Pain: "He deflected my Almighty Push!"

Obito: "I just wanted to create a world where Rin exists, but that bastard Natsuki said wherever there's Rin, there's bound to be Kakashi. Then he made me watch Kakashi's Kirin. That absolute bastard!"

Six Paths Madara: "I declare Natsuki the strongest!"

Black Zetsu: "Natsuki, you bastard! Stop stepping on my mom's head!"

Natsuki: "All I've got are the Eight Inner Gates, the Flying Thunder God Technique, and Sage Mode. That's enough to make me the strongest in the ninja world?"
