After transmigrating to the world of Naruto, Uchiha Mingyu became a member of the Uchiha Clan. He gradually realized that no matter how hard he trained, he could never surpass the genius Itachi.

All I have is Fire Style: Fireball Jutsu? I'll make my first top-up of six yuan and get a budget version of Planetary Devastation. Not enough chakra? I'll make up the difference with money, and show them what a chakra-ton looks like. Not enough attack power? Kirin in my left hand, Rasenshuriken in my right.

Tobirama: Big Brother, I suggest adding the whole of that evil Uchiha Mingyu to the Scroll of Seals.
Hashirama: Is this even human? My chakra's been completely drained!
Kakuzu: Wait, where the hell is my money?
