She reluctantly agrees to go naked.

After thinking about Yuri's suggestion for a while, Constance decided, if reluctantly, to try it out at the very least. Yes, it was crazy for her to strip down naked just like that, but she had nothing to lose doing it, and considering her current situation, this might be the only way she had to return to fódlan.

"Alright, alright, i will try to do it at least", Constance replied to Yuri, "But you better not say anything, correct ?", she added.

"ok, i promise i won't say anything", responded Yuri, and so,with his silence asured, Constance slowly began to do the deed.

The first thing she needed to do was to remove her dress and accesories, which was a lot more difficult for her than it sounded, likely because she didn't want Yuri to see her underwear, which seems a weird thing to say at first, given that she was going to be naked anyway, but considering that she knew that while Yuri wouldn't be able to her naked privates, he would be able to see her underwear, it made sense.

"C-Could you please turn around ?, i don't want you to see me stripping", said Constance.

"If you wish so", replied Yuri, upon which, he turned around.

With that out of the way, Constance then slowly removed her dress, as well as all the accesories she wearing one by one, dropping them all in the floor along the way. A few minutes later, she was now only wearing her black underwear, the last articles of clothing she wearing, making her even more self-conscious than before.

At first, she wanted to stop right now, for if she was now getting very embarrased in only underwear, she couldn't imagine how embarrasing it would be for her to be naked. Yet, at the end, following some deep breaths and meditation, she then decided to finish what she started, "Ok...Constance, let's do this", she said.

And so, with renewed confidence, Contance then unclaped the straps of her bra with her hands, dropping it in the floor along with her other clothes and leaving her topless in the room. The only visible thing left of her, as well as the last thing protecting her modesty, were her black panties, which, just like her bra, fell in a quick swoop, as Constance put her thumbs in her sides to take it off.

Following the sound of her panties dropping in the pile of clothes, Constance was now left completely naked in her laboratory, upon which, thanks to the effect of the invisibily spell, left her also completely invisible to everyone, however, that didn't stop her from feeling the wind and the cold in her lower regions.

Having now discovered the secret to (almost) total invisibily, the naked Constance knew that she had many paths open to her, she could either chicken out to continue working on improving the spell..., or..., she could embrace this side of the spell, and the many opportunities it grants to finally return back to Fódlan and restore the power of her house once and for all ?
