Hello everyone, I would like to give you some background currently.
1. The oldest person in the Haruno clan is Akise because he was Sakura's servant. He is Itachi's age. The rest of the people in the clan are Sakura's age or younger.
2. Inner Sakura will appear more in the Land of Waves Arc. That will be in a darker perspective since Sakura is connected.
3. The ages are canon besides the OC's who are not in the original Naruto plotline. Yes, Kono was around the same age as Kakashi now when Kakashi and Sakura would interact.
4. Haruno clan. They are basically exiled from Konoha, even though Sakura is now the head of the clan.
Ask questions if you want but I won't give a direct answer to any that might give away the story. Ja ne~
