- Anyways I think a filler that took place in one of the other 4 main nations so we could learn something new about them.
Maybe another Sand Sibling arc with Gaara's former student and Temari going on some critical missions.
Or a flashback arc where we see Jiraiya in his younger days traveling but I cant get into this too much because of spoiler limitations here.
something with the young Sannins and the Third going on mission and half way through the Filler they become of age(adults) and go on mission in the War
and they cant do flashbacks like itachi and stuff because they dont know if the autho of manga will write those flashbacks later in his manga, so if they put it in the anime how stupid wouldnt it be when author writes something totally different in his manga and then they have to put that on scree nas well
it would be an idea for a filler ep if they had it based on the akastuki. Would allow viewers to get a better understanding of each individual member and c where they originated from and etc.
