Jin blinked several times at Sakura, their expression going from 'street tough' to 'lovestruck teen' in an instant. "Whoa, Sakura-chan, you... whoa." Jin cleared their throat, and tried to focus. "On the subject of weapons... Don't ask me where I got this, I won't tell you, don't ask me if it's legal, it's better if you don't have a direct answer, but-" In Jin's bag, beneath some more food was what looked like a heavy duty sling and a bunch of metallic balls. 

"If anyone needs something rigged up, just tell me. I'm getting pretty good at it, and my aunt and uncle are just glad I have a hobby that keeps me out of trouble." With a wicked smile, Jin loaded the sling with one ball, set their eyes on a tree branch, exhaled and pulled back, hard. The ball flew and the branch cracked like it had been shot. 

"...well, at least it keeps me happy."
