Reincarnated into the world of Naruto, Tetsuya Chiba starts out with a money-grubbing system. All he has to do to get stronger is top up and pull cards.

Husky System: "Pfft. You're this broke, and you still call yourself a transmigrator?"

Tetsuya Chiba: "Quit looking down on me, you mutt. Take a look at this!"

Tetsuya pulls out a huge pile of banknotes.

Husky System: "Oh my! If it isn't my dearest, sweetest, most beloved master! How much would you like to top up this time?"

Tetsuya Chiba: "Max it out!"

From that day on, the ninja world gains a man who values money more than his own life.

Kakuzu: "A kindred spirit! Tetsuya is my kindred spirit!"

Danzo: "Tetsuya, I'll pay you. However much you want, I'll give it to you-even Konoha's entire treasury-as long as you help me drag that monkey out of the Hokage's seat."

Black Zetsu: "I'll pay you. Could you help me rescue my mom?"

Tetsuya: "What? Who? Don't you know she's the progenitor of all us shinobi?"

Black Zetsu: "Then what would it take for you to agree?"

Tetsuya: "That'll cost extra."
