Quick recap
Filler arc. Naruto meets Menma, a man with no memory, and the two set out on a mission with Neji and Tenten. Menma helps the group in every fight and seems like a decent guy, but bit by bit his memories return and reveal he used to be a bandit. He doesn't want to be that man again. When the town they're protecting is in danger, Menma triggers a rockslide that saves the townspeople and dies doing it. The town survives thanks to the man he chose to become.
