The story of shinobi was one of immense sacrifice as men and women of great power and will clashed to create the world we see around us today. The scars of those battles that redrew the borders of great nations are still visible to this day.
The stories of great warriors like Senju Hashirama and Uchiha Madara are told even today, a century after they've passed away.
And if you want to hear their stories and the stories of brave warriors like them, then I suggest you go read a damn history book.
This story is not about them, it's about the life of a weak ninja, who never sought battles or accolades. Did he live up to his full potential? Probably not. But did he try to have fun living his life? You bet he did.
