Mayonaka

They were shinobi.
Children shaped into weapons and raised to protect those who could not defend themselves. Everyone believed the greatest dangers came from the outside world. Yet Sakura Haruno soon discovers that the most deadly threat is growing inside the very walls that were supposed to keep them safe.

As the newest generation of genin trains for the future, hidden truths come to light. Secrets unravel. The village that once seemed bright becomes darker with every step she takes into its shadows.

Mayonaka means "Midnight," and this world is a parallel version of the one they know.
In this timeline, there is no Uchiha massacre.
Nothing is simple.
Nothing is clean.
