Team 7- 4 Man Squad?!

What if Sakura Haruno disguised herself as a boy?

Was ANBU but returned to the academy after some orders.

Almost no one knew HE was actually a SHE.

Almost no one died, the Massacre, Kakashi's Friends and Naruto's Parent did not happen.

But something did happen, Sakura's parents died.

Training to get revenge on the man that killed her parents she is training disguised as a boy.

Thus, she starts the academy.
