I don't think this is actually undressing, as Jersey Girl never seems to be wearing pants or underwear. It's the best part of the show.

Indeed, seeing the position of her hands, it's quite obvious that Ako is trying to force Shizuno to wear pants, for modesty's sake, and to the despair of the viewers.

I wish Shizuno seems to wear a buruma.

Doesn't look like Ako is wearing pantsu either

Some say that no character in this show wears any sort of underwear.
But there's no proof of that, but there's also no proof of the opposite.

I suppose one of the specialties of the show is the "not a pantyshoot".

Other is the yuri love, in much more quantity than the "no pantyshoots"

... ah! there's also the mahjong...
(don't know why, but I almost forgot the mahjong. strange)
