On How the Uchiha Became One of the Three Great Families

Currently planned as no-cp, with multiple one-sided crushes.

She accidentally transmigrates into the high-risk world of Jujutsu Kaisen. The good news: she's become an Uchiha. The bad news: the System tells her she has to make the Uchiha one of the Three Great Families.

But why did she have to land in that chaotic age a thousand years ago? She's not ready to fight Sukuna yet! To keep her alive, the System hands her an old geezer. Tsumi is instantly even more furious. What does that mean? Does it think her chances of survival are still too high?

Then she takes a look and sees that the old geezer is Uchiha Madara. Well, in that case, never mind.

And then, a thousand years later...

What do you mean Uchiha Madara has been resurrected through Impure World Reincarnation and is going to participate in the Culling Game?

Kenjaku: Sure.
