I Failed to Become Hokage, So I Had to Unite the Shinobi World

After transmigrating into the Uchiha Clan, I was determined to make the red flag fly across the entire Shinobi World.

Under the guidance of Uchiha Youlin, the Shinobi World gave rise to Jiraiya, godfather of entertainment; Hiruho, who ascended through machinery; Orochimaru, the mad scientist; Tsunade, the medical master; Deidara, the demolition genius; Mei Terumi, the relationship guru; and the one who split mountains to save his mother...

Of course, the new Shinobi World has no handouts for old geezers. Hiruzen Sarutobi, Danzo Shimura, you bunch of old fossils, cough up some cash!

(Slow burn, no breaking up canon couples, no out-of-character behavior, one female lead, kingdom-building)
