Naruto: The Uchiha Resurgence

The Uchiha clan is just a bunch of lunatics! Arrogant, paranoid, easily emotional. Itachi and Shisui have been brainwashed into shapes of Konoha, and to make things worse, the clan head Fugaku is an indecisive guy. The transmigrated Uchiha Seiya feels a lot of pressure. Just when he sees the Uchiha about to slide into the abyss of destruction and plans to make a run for it, the system suddenly arrives!

System notification: The system has been delivered!

Since that's the case, then I'll just rise from the coffin!

"Fugaku, an indecisive fellow like you should step down! Shisui had his eye gouged out? Then we'll directly storm the Root! The police force gets complaints? Then arrest the complainers too! Don't accept? Then fight, the bigger fist gets the say! Five Susanoos charging ahead, I don't even know how we could lose!"

The domineering Seiya suppresses Konoha's F4. Let everyone know, the fist, is power!

The Uchiha no longer want to be Hokage. Konoha, you still expect them to risk their lives for you?

Third Hokage: "Oh no, Seiya has sold out Konoha!"

Fourth Kazekage: "Huh? Where's my huge One-Tail Jinchuriki?"

Fourth Raikage: "Damn! Can't beat him, his fist is harder than mine!"

Third Tsuchikage: "It's over, this deal seems to have been a loss!"

Fourth Mizukage: "That was close, almost lost my life."
