Tbh, after giving it some thought… a Sand Arc Mission would be somewhat “pointless” until we find out what Matsuri was doing there in the first place.
- Gaara is injured but alive.
- The Sand Village may be somewhat damaged but operable.
- Konoha only knows one way to reverse the Tree Shindig, and not even in full detail (What happens “after” getting a TSB).
Unless it’s a “Shinju Pursuit” mission, going after Ryu & Co, it doesn’t make sense to send a squad unless its like Sakura or someone to heal Gaara.
I hope it is a Pursuit Mission though.
