I've kinda already asked this, Yukikaze, but what are Adult Panties?

I don't quite understand it myself, but you can leave it to Yukikaze! I have some knowledge!!

Shimakaze-chan never changes, so she's prepped for victory every day!

It seems that Adults have this thing called 'Victory Panties' - a trump card that no one can stand against!
