The Female Lead in This Crossover Is No Good Person

This story is also known as [The Protagonist's "Sister" Is a Scheming Bitch] [Yes, I'm the Legendary Mary Sue] [Girl, You're So Badass, Does Your Mom Know?]

Madara said arrogantly, "Drown in the Infinite Tsukuyomi!"

The heroine smiled innocently. "Wake up, foolish human."

Obito: "...That's not the kind little angel I know. It can't be!"

The Nine-Tails: "Who can you blame for being blind?"

Wu Se said, "There are so many kings in this world. It's so annoying. There should only be me, haha!"

The heroine furrowed her brows. "Child, what you're doing is wrong."

Then her style changed completely. "Ahahaha! All you kings can go to hell! The Empress herself is all we need! Ahahaha!!"

This is the story of a fake Yamato Nadeshiko who transmigrates into the older sister [younger sister] of various protagonists. It's the story of a nutcase trying to steal the villains' jobs. The morals are questionable, so read at your own risk.

The worlds currently planned are Naruto, K, Durarara!!, and possibly others. As for the couples, that's still under consideration [laughs].
