I guess Shimakaze's skirt wasn't micro enough for Amatsukaze's liking. Got to get that full on upskirt.
Now I'm half remembering a joke from a manga or doujin about panties. Something like panties on full display all the time are meaningless and the appeal comes from having to work for even the slightest panty peek.
I'll have to make a mental note to check the Quotable Dialogue pool for it later. Edit: Found it.
