That sucks big time! :rofl: Just kidding. I had to say that when you put in constructive criticism welcome
Truth is, that was a fantastic opening! I did have one suggestion (although you've probably already thought of it)
It would be good to have one comical scene in the midst of this pathos (like Naruto saying something and sakura bopping him on the head) and then getting right back into pathos... I'm not very familiar with Naruto development in stories (I've only finished watching about 80 ep until hokkage 3 dies) but I've not seen Naruto in a drawn out serious scene unless its fighting...
Like I said you've probably thought of it already though
... Great going Koku-kun! We'll be expecting more of this thread to be updated soon enough
