I'm a Bad Woman in Naruto

A shut-in transmigrates into the world of Naruto and unexpectedly becomes a girl, setting out on a path of no return.

Uchiha Madara: Bai Ling, dance with me!

Uchiha Feng: Ling-chan, I love you! I want to marry you!

Yu Ling: The Empress belongs to me alone.

Bai Ling: The only person who can marry this empress is me.

Get married? Not happening. Once I’m strong enough to defeat Madara with one hand, I’ll be able to do whatever I want.

(The ending is gender-bending, as the tags say. Read without worry.)
