The Seventh Hokage has fallen.
But at the moment of his death, he seems to awaken a new ability: to witness the lives of those who have passed away.
Darkness, corruption, and deformity. The disasters, both natural and man-made, that plague the Shinobi World leave him lost and confused. Was everything he did really right? It seems not.
What else could save the Shinobi World?
He thinks of an old friend from years ago, someone strikingly like him who liked to wear a mask...
He finds a man who can help him change the world. With that man's help, he returns to the past, to a time when... everything can still be changed!
(No alternate universe, no out-of-character behavior, no mindless decisions, and no tired cliches. The story has solid logic, neither vilifies nor glorifies anyone, and includes a little conspiracy theory. There are quite a few original interpretations. If it's not to your taste, please be gentle T_T.)
It's all private design and doesn't suit Naruto
It's all private.
The writing is pretty good.
Throughout the whole story, I created a lot of ninjutsu and concepts myself, which looked very confusing.
