The mysterious girl that showed up out of nowhere was actually Filo. She's a filolial queen with an advanced transformation ability, and she can even take human form thanks to it. However, her clothes get ripped every time she transforms, meaning Naofumi has to get her some magic clothes if he doesn't want to go broke. The party leaves on a new adventure to gather the materials required.
You mean you'll take 
everything but our lives?
أتعني بأنّكم ستأخذون كلّ شيء باستثناء أرواحنا؟
Aber alles außer unserem Leben
würdet ihr uns nehmen?
¿Y se quedarán con todo lo demás?
¿Y os quedaréis con todo lo demás?
Pour que vous piquiez
tout ce qu’on a ?
Nel senso che ci porterete via tutto il resto?
Está dizendo que vai pegar tudo,
tirando nossas vidas?
А всё остальное, значит, отберёте?
