Many want to hear how hashirama will respond to sasuke's question.
Well i have an idea of how the answer will look like. I will be using my favourite character;JIRAIYA . Well during the period when naruto learnt rasengan, they had an encounter with orochi and kabuto and jiraiya told orochimaru who a shinobi is. This was what he said;
" You're wrong, that's not what makes a shinobi. You never did get it, a real ninja is one who endures no matter what gets thrown at him... Let me explain something to you, there is only one thing that matters if you are a shinobi, and it isn't the number of jutsu you possess. Allyou do need, is the guts to never give up"
That was jiraiya's response and i believe hashirama will only add more to it. Hashirama is strong, humble and funny just like jiraiya and naruto. An apple does not fall far from the tree. Think about it and post your reply on this thread
