Naruto: I Became a Legend in the Ninja World Through Sign-In

I woke up as a nobody on the fringes of the Uchiha Clan.

I checked in at Hokage Rock and got Kage-level chakra as a reward, then the ANBU arrested me.

I checked in at the interrogation room and got S-rank mental defenses as a reward, leaving the interrogator dumbfounded.

I checked in at the Hokage's office and got mastery of all five nature transformations as a reward, making the Third Hokage drop his pipe.

It's not that I'm showing off. The System keeps sending me to places more exciting than the last.

Only later did the shinobi world realize this guy had never trained at all. He could just lie flat every day and still get by.

Uchiha Rei: I just wanted to check in, but they insisted I become the savior of the world.
