Gintoki, Shinpachi and others in “Unfinished Business”

Regardless, our ancestors never paid no mind to underwear, nor did they wear it. In other words, one could do whatever they liked. Even the princesses were valiant like generals under their kimonos!

That's actually not a bad contradiction.

Even when they seemed docile on the outside, they still were like a shogun on the inside. Or barbarians in-- [Otae interrupts him by punching his face.]

[deep, serious voice.] I don't want you to bother me with your "no underwear" theories. That darned thief stole my favorite "battle panties", the pervert!

"Battle panties"? You planned to fight somebody?

Exactly. I may need my full strength to settle the score. Never judge a book by its cover.

[still with Otae's fist buried on his face.] And what will that get you? Would it satisfy you to get revenge in a duel to the death just to recover something you lost? Is that acceptable, if only to recover your panties?

[with an evil smile.] It's not just the panties. I'll catch him and make him bleed.

Sister...!

That's not something a civilized, panty-wearing girl would say. I'd say that's the kind of thing you'd expect from a naked hunter from centuries ago.
