Kunoichi Chronicles

Even if Orochimaru turned 'good' and has been dead for many years now his legacy is still around. Daku, a boy without a last name stumbled over one of Orochimaru's very old almost forgotten hideouts. He found the knowledge there irreplaceable, and decided to continue the work of the genius he never knew.
Enter the next generation of shinobi. We follow Hanako Inuzuka, Jin Senju and Maiko Sarutobi in their journey to become real shinobi and fight for the peace their parents have had for so long.
Hanako is strong but unmotivated in most things.
Jin is a healer who doesn't like fighting.
Maiko is a hothead but she cares for her friends more than anything.
They are just starting their journey.
But Daku has found an ally. The Land of Void. A large nation across the ocean due east and the homeland of Kaguya Otsutsuki. The land lost to time. Not only is Daku the first person they've had contact with in many centuries, they bare a grudge against the lands of the west for the death of their princess Kaguya.
