Things are a bit more somber for a while after that. Naruto reports Sasuke withdrawing and getting sad; Kiba reports him getting into fights with other kids left and right. Mostly Naruto, but also a few others. Sasuke seems to have gone from 'shy and sensitive' to 'cruel and cold.'
Tsume takes extra care in training her kids - and in making sure they are kids. She refuses point blank to have Raizume admitted early to the Academy, no matter her genius. She makes sure Hana knows she doesn't have to push herself - Hana thinks for a bit and confides, quietly, that she thinks she'll be happy at chuunin, as a clan vet, she doesn't think she wants to be head even though she knows the clan needs someone -
Tsume hugs her, says, yes of course. They'll figure something out - Kiba or Rai or a cousin as the next head, family is family is family and the Inuzuka aren't picky about the lineage of who acts as their face to the world.
Eventually things lighten back up a bit. People move on, and put things out of their minds. The empty places where the Uchiha were get eroded away.
Eventually, it's Rai's turn for the Academy.
