I disagree with the point of threatening Mira.

Without Mira being seriously hurt in the process, Erza is very unlikely to cave in. Kyouka obviously has plans for Mira, so doing serious damage seems out of the question. And just threatening to hurt Mira without being willing to actually do it would just undermine Kyouka's ability to gain information on top of being a waste of time, if Erza called the bluff.

So no, theatening Mira has very little chance of being helpful, but a very good chance to be counter-productive to Kyouka.

And I think you really mistake the situation here. Sure there are many ways to torture Erza without stripping her, but look at reality and you'll see that stripping her is the most logical and effective way in this case. Stripping her before torture is just how things are "usually" done and not doing it would require far more explenations than just going with it.

Saying that Mashima did it out of pervertedness is a rather harsh insult in this situation and I really think you should dail it back a bit here. Calling someone a pervert who likes to draw naked women in bath and such is one thing, but insinuating he get's excited over drawing naked torture scenes is something very different IMO.
