Konoha: The Thirty-Year-Old Uchiha Can't Be Bothered

"Age thirty. That's when the system finally decides to activate—but the host wants none of it. A furious barrage of "NO!" sends the system into an indefinite cooldown, with one cruel penalty: he will remain thirty years old forever. In Konoha's second year, just as Uchiha Madara prepares to leave the village for good, he is stopped by a curly-haired cousin, Uchiha Gin. Madara steels himself for a farewell argument, but Gin simply presses a storage scroll into his hands, urging him not to stint on travel expenses. Years later, after capturing the Nine-Tails, Madara idly opens that forgotten scroll—and finds himself staring at a mountain of gold bricks and several unfamiliar ninja tools, his mind churning with questions. This is a story that gleefully tramples canon, packs in more tokusatsu references than any Naruto fanfic should, and runs on pure reader headcanon.
