Naruko Inherits Shiro's Power as the wretched Egg
She Can manipulate blood to any form she wants and have all the abilities as all known deadman characters who gotten the branch of sin.
Has a bit of that crazy look when adrenaline up pumped or lots of blood. Her mentality is back and forth with her manipulating others and revealing her crazy side (due to mob attacks and at a really young age finding out about her having the kyuubi inside her. It shatters her mind and kills everyone. Becoming Sadistic, twisted, etc.).
Have her blood mix when she injects it into other people's blood as a virus to consume and replace their DNA as they die as her own to keep extra packs of blood just in case anything stronger removes her usual supply of blood that she does
Uses seals to store the extra blood on her body. Can manipulate her blood just like how gaara does.
Bash evil civilian council, Sasuke, Sakura.
Naruko can be paired with Tayuya where they encounter each other in any way you want in the story and Tayuya is an uzumaki in very distant cousin from the clan that fled at the time. Tayuya can get later on the branch of sin powers through Naruko bestowing her with the branch of sin and when getting the mate mark will increase her powers. Replaces Tayuya's curse seal and makes it slightly more powerful with more benefits and keeps her transformation form.
You can choose for naruko to stay in Konoha or have her leave and try to rebuild her clan village.
Naruko must learn Sealing arts and later on when she gets more info about her Uzumaki clan. creating seals is like art so add whatever from trap seals to seals that augment armor or weapon or body. Even using seals on gloves to make jutsus quicker to cast without needing hand seals.
