Despite her lack of face, she visibly perks up at Haru's interest in her mention of rifles. Yes, let her talk about guns please!

"Among other things! Here, why don't ya take a look?" She pulls out the weapon, moving her drink aside so she can lay it flat on the table. (Don't ask where she got that rifle from if Haru didn't see it before, ssshhhhh, spacey-wacey wibbly-wobbly.)

"This here's my fav'rite gun, and the only one that came with me. Course, it ain't been workin' since I got here, short o' that one time we all fell asleep." She crosses her arms in frustration.

"If it don't start workin' soon, I might have to make myself a bow or somethin'. I miss shootin' things."

...She doesn't mean that in a violent way, it's not like she wants to shoot living things. She'd be happy with inanimate targets.
