The Strongest Kunoichi: Starting with Naruto's Twin Sisters!

Reborn in the ninja world, reincarnated as Naruto's twin sister, with the Yin Kyuubi sealed in her body. The Yin Kyuubi is very friendly to me, and wants to break through the seal and kill me every day. But it never defaulted on the rent, paid it whenever I asked, and never minded whether there was a limit on the rent. I was also moved by its active attitude towards paying the rent, even if it was paid thirty times a month. However, these are not the important points. The important point is that I was a man in my last life, but in this life, the bottom is gone, gone, really gone, gone, and it still leaks!
