Very amusing! I can't resist a good chain-of-people-hanging-over-a-precipice. Of course, Yuffie has only herself to blame for her particular situation... Maybe this will teach her to keep those shorts buttoned up from now on. I love the comical anxiety on her face.
It's almost unsurprising that Tifa wears panties with so tough they can support her entire body weight, given that her gloves are actually used as weapons. She's gonna have one heck of a waistband mark afterwards, though.
Quite the wacky situation, thought it looks like Tifa got the worst of it. Still, she should be grateful she didn't fall... 'course that might still be a possibility if her undergarments don't hold out.
