His father--->Namikaze.
And that's it.
And yet he is called a Uzumaki....
I mean he is half Uzumaki and half Namikaze.
For two documented reason he took his Mother's last name over the other.
1. To disassociate him from his Father so he isn't targeted.
2. His mother's clan name had more claim in inheritance due to being more notable.
Who killed his Parents?
Obito did...
Who is close to Obito?
The white Zetsus...
Madara can see things with his rinnegan and yet all his enemies not him for his Uzumaki lineage.
