Note. What I will do from now on is show you guys what happens in the story in the form of memories, that's why there will be time jumps between the memories, I think there will be at least 5 chapters based on this, where I will take advantage to make the bases of the story and prepare it for the "Naruto Era".
I will explain binding vows and show characters who already have connections with Kenny, probably the next memory is the death of Tobirama and then the Kyubi attack, I don't know specifically when the Kyubi attack will be, probably the last chapter of the memories, and believe me Kenny will not shake his hand when taking some bodies.
