This is a scene from my fanfic "The Adventures of Haruhi Uzumaki" (Google Haruhi uzumaki fanfiction to find it :D)

The scene involves Naruto watching him and Sakura's daughter during the Genin Exam. But an attempted asassination occurs on Naruto, since he's the Hokage's successor, involving him being stabbed, and paralyzed temporarily. Before the final blow was struck, Naruto's daughter: Haruhi intervenes, and her being brave, decides to fight off this assassin in order to protect her father.

If you're all for a good read, then this one's the game ;)
