i have been deliberating on this and the only things i can come up with are 1) his sword, 2) naruto's jacket that he found after naruto vanished for the month (a pretty gay option but idk if he'd push THAT hard to get it back), or 3) his scratched hitai-ate/forehead protector. 1 and 3 he'd definitely want back if only for ninja-related reasons. 2 he might just abandon because he's tsun.

scissors+holster would be funny but not sure if Syo would come into play/if you'd want her to?? what sort of content would be on the manuscript... sasuke would probably just throw it away LKMFSLKFMSD
