PLOT
I'm trying something new, so bare with me.
This storyline takes place when the Naruto gang are still in the ninja academy just before they are assigned their teams of three. Nothing regarding who is on what team will change. What will change are the scenarios in which the teams will be placed in. For instance, Naruto's first mission will be in Hidden Mist, but how things come about will vary due to the new family situations and how they affect the characters?
The main points in this RP will revolve around the situations in Konoha.
In this RP, Itachi never killed the family. He lives with Sasuke and the rest of the Uchihas as normal as it would have been had he not gone through with the massacre. I'm not saying there won't be family conflicts. That would be dumb; of course there will be, or else Itachi wouldn't be Itachi. Now, will he kill them all in the future? Well, that's up to we, the RPers and he or she who plays Itachi.
As far as Orochimaru goes, nothing about his past involving Konoha, Jiraiya, or Tsunade is different. However, since Itachi never killed the family and never left, he couldn't be part of the Akatsuki, therefore Orochimaru couldn't have met him or personally known him. That doesn't mean he couldn't have heard of Itachi. Knowing all this, would Ororchimaru chase after Sasuke or Itachi? Both? Neither? Again, it's up to we RPers and he or she playing Orochimaru to figure it out.
