Naruto: God-Tier Power-Up System

I transmigrated into the Hokage world and became the grandson of Kagami Uchiha and the younger brother of Shisui Uchiha.

Seriously? This identity comes with a ridiculous amount of pressure.

Luckily, transmigrators always get a golden finger: the National Enhancement System.

Who am I? What status do I have? Make me overpowered, will you?

The National Enhancement System is dead, the enhancement is dead. The Iron Rank Supreme is here!

An Iron Rank +12 Enhancement Scroll? No worries. The Ancient Tome is a sure bet. Hey!! It worked, it worked!!

The Great Fireball Technique is so weak? I'll enhance it to +12 Red, making it about as powerful as Madara's Great Fire Annihilation.

Bad at taijutsu? I'll enhance it, then train in the Eight Gates.

Only a two-tomoe Sharingan? Enhance, enhance, and I'll go straight to the Rinnegan!
