Naruto: Starting as Tsunade's Desk Mate

Living in Konoha, I start out as Tsunade's childhood friend. This is a situation I must defy fate to change.
Forget the tragedies of World War II and World War III, forget the decline of Konoha, all of that is forgotten.
I want to hold Tsunade's hand and walk step by step to the pinnacle of the ninja world.
Madara Uchiha, Kaguya Otsutsuki, come at me if you dare!
