Naruto: More Children, More Blessings; Naruto Turns Eighteen in a Day

I transmigrated as Naruto just before the Ninja Academy graduation exam, and awakened the [More Children, More Blessings System] and the [Ninja World Hot-Take System]!

Overnight, my body matured instantly into its peak eighteen-year-old form! I stood six feet tall, looked better than Minato, and had chakra reserves on par with a tailed beast!

The Third Hokage, Sarutobi Hiruzen, personally confirmed it: “His bone age is eighteen, but this really is Naruto!”

To make him easier to monitor (crossed out) train, the Third Hokage reluctantly shoved eighteen-year-old Naruto into Team Seven, which was full of twelve-year-old brats.

And so, the whole vibe went off the rails.

When Kakashi showed up late, Naruto delivered his hot take: “For an elite jonin, having no sense of time is a sign of kidney deficiency.” In reward, he received [Flying Thunder God: Second Step].

Faced with Kurenai Yuhi’s genjutsu, Naruto turned the tables and pinned her against the wall. “Big sis, the genjutsu is fake, but my heartbeat is real.” This triggered a [More Children, More Blessings] side quest.

Sasuke: “We graduated together, so why do you look like my uncle?”

Hinata: “N-Naruto-kun has grown up. I... (faints)”
