What is the most bravery ever displayed in the entirety of the Naruto story?
Go deep here, guys; don't just think of the big parts... think on the lesser mentioned moments as well.
I'll start with two.
1. The moment Hinata challenged Nagato. Think for a second: Hinata has very low reserves of confidence in herself to start with. She just watch a single shinobi obliterate her village and combat and defeat some of the greatest shinobi she knows. Despite being at a depressingly low disadvantage, she placed herself between Nagato and Naruto and prepared to die.
2. Kurenai vs. Itachi. I mean, really. Kurenai voluntarily chose to go toe to toe with one of the deadliest, most prodigiously talented ninja alive. Most shinobi would evacuate the premises at the mere sight of Itachi Uchiha. Props.
