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.
If nothing else, I can tell 
he won't be easy pickings.
ومن الواضح أنّ إقناعه ليس سهلاً
Zumindest ist klar, dass wir ihn nicht

Solo sé que me conviene
no bajar la guardia.
Solo sé que me conviene
no bajar la guardia.
Bref, j’ai compris
qu’il faut rester sur nos gardes.
Comunque sia, si capisce chiaramente
che è un osso duro da affrontare.
De qualquer forma, sei que
não posso baixar a guarda.
В общем, расслабляться против него
точно не стоит.
