Please reference the Lucky Bag in the Adult 6th DesDiv series.
Actually-A-Lady Akatsuki would likely refuse because she already owns a pair, and Ikazuchi would probably think underwear like this is pretty tame compared to her crotchless pair. It wouldn't fit Inazuma, and there'd be a 50/50 chance of her buying something crazier because "it's the only thing that fits", or using the same logic, owns something stupid-looking but is sexy anyway because "I have giant tits, your argument is invalid". Hibiki would just be buying herself underwear at a discount.
I feel like Hibiki would have at least one set she can tease with.
Heart not in it, eh?If you'd just throw it on for a spell, snap some pics and send them to the Commander, then...Wait! That didn't count!Final Battle-Use Equipment ReturnsWha? Really!?Ah, I'll be giving this one to you again this year, Akatsuki.If you're going to go on and on about that, why don't you just do it yourself?
