Naruto: Cards on the Table—I Just Want to Slack Off with Tsunade

"If doing nothing is an art, then I'm the pinnacle of the art world."

Uchiha Shinichi transmigrates into the Naruto world as a member of the Uchiha clan. Born with dead-fish eyes and a lazy disposition, he refuses to hustle or join the rat race. His dream is to eat sweets, sleep, enjoy the scenery, and open a ninja-world dessert shop while doing a few minor missions to make ends meet.

Unfortunately... the system won't allow it!

Host, mission assigned: Save the ninja world!

Shinichi: "What's that got to do with me?"

Refuse the mission, and you'll turn into an actual dead fish.

Shinichi: "Fine. Then at least give me a decent reward, okay?"

Congratulations, Host! You have received: Lake Toya Wooden Sword!

Shinichi: "???"

He thought he was just the system's errand boy. Instead, he somehow coasts from victory to victory, all the way to the pinnacle of the ninja world-

He accidentally invents the "Six Styles of Konoha" and becomes a taijutsu legend!

He casually creates the "Rasengan," leaving Jiraiya so frustrated that he drops to his knees and begs to become his disciple!

He inadvertently awakens the Mangekyo Sharingan, and Madara Uchiha claws his way out of the grave to take him as an apprentice!

One day, he lets out a yawn-only to discover he's become the ninja world's God of War!

The Uchiha clan: "You're clearly the strongest, but you're too lazy to lift a finger?!"

Tsunade: "You have the power to protect the world, and all you can think about is eating sweets?"

Everyone in the ninja world: "Tell us! How on earth did you do it?!"

Shinichi spreads his hands. "Don't ask. If you do, the answer is that I'm a born slacker. If I can win lying down, why would I bother running?"

-This is the story of how one dead-fish-eyed slacker sets out to coast through life in the ninja world, saving the world along the way.
