The Last Namikaze? Sasuke Or Sakura × Oc(reader)

Kasumi Namikaze or Uzumaki, depending on what generation you are from.

Kasumi Namikaze, the eldest daughter of Minato Namikaze and Kushina Uzumaki. Or also known as The Yellow Flash of the Hidden Leaf and the Red Hot-Blooded Habanero. These two are so happy to be parents of the baby girl, but her birth came with many concerns.

Kasumi was born premature, her chance of survival was pretty low, and her birth was pretty easy for Kusina, and keeping the nine tails in check was simple. With no trouble, meaning so attack, at least for now.

Her chances of surviving were low, but surprisingly, not at zero since she had a bit of Kurama's chakra in her system. The chakra always and somehow healed her premature body. No one knows how it works and why it worked, not even kushina. But she was glad her baby girl was alive.

Following their death, her baby brother was born, but no parent were next to her to help her keep them close.

Now the third hokage was forced to make a decision to keep the siblings together or separate them.
