Exclude me Uchiha? Sorry, we quit!

Whoever the garrison likes will go!

“Kakashi, Danzo was the mastermind behind White Fang’s death and was connived by the Third Generation. You actually worked for Konoha!?”

“Itachi, this time I will awaken the Eternal Kaleidoscope for you.”

“Bai, your actual combat ability is too weak. Please enter the Tsukiyomi space to practice for a few years.”

Sorry, we Uchiha have kaleidoscope per capita.

Who can fight in a group fight these days? Get on my shoulder!

Otsutsuki is coming to destroy the world, but you are still striving to be Hokage. There is something wrong with you.

Danzo: “We must not allow Uchiha to gain power!”

“Sir, Uchiha Fugaku has resigned from his position as captain of the Konoha Guard.”

“???”

Third Generation: “The position of Hokage will never be given to you as Uchiha!”

“Hokage-sama, Uchiha has withdrawn from the Hokage campaign.”

“???”

“Sir! Uchiha has established his own country!”

“What!?”

“It’s not rare for us Uchiha to use a Hokage as a treasure. Let’s wait and use him as a target.”

ps: Hizashi did not die simply because he wanted Neji to have a father.

- Description from novelbuddy

What would you do if you reincarnated into a doomed novel?Would you rely on a system to get stronger?Steal the protagonist’s opportunities?Kill your future enemies before they even rise?I had none of those options. I only read the free chapters.No cheats. No system. No future knowledge.But that doesn’t mean I’ll wait for death.If the world won’t give me a way to win—I’ll just carve one with my own hands.* * * * *Note: R18 isn't for detailed sexual content, but for dark theme, gore and all.
