Naruto: I Monopolize the World, but I'm Not a Ninja

[An overpowered protagonist, no pandering to the original cast, dark tone.] The System broke down as soon as I arrived in this world. Who knew I could still inherit its power? Doesn't that make me the System itself? Why become a shinobi? To make money? I'm already the richest person in the world, so why bother being a shinobi? Kakuzu: “The only thing I like in life is money!” No problem. He's a born wage slave! He can use all five hearts however he likes, without worrying about dropping dead from overwork! What's the most important thing in this world? Connections, of course. Money is a connection, and I'm invincible on top of that! Changing the plot lets me recreate the world, so let's see who really gets to call the shots!
