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.
And? You didn't come here just to 
show off this filolial queen, right?
وبعد؟ لم تأتِ إلى هنا لتتباهى بملكة
الفيلوليال هذه، صحيح؟
Ihr seid doch sicher nicht nur hier,
um mit eurer Königin anzugeben, oder?
Pero no viniste a presumir
de esa reina, ¿verdad?
Pero no has venido a presumir
de esa reina, ¿no?
Et donc, t’es pas venu
juste pour te pavaner avec ta reine ?
Non sei venuto qui solo per sfoggiare
questa cosiddetta "Regina", vero?
E? Você não veio aqui só
mostrar sua Rainha Filolial, né?
И? Ты же не покрасоваться
эту королевну ко мне привёл?
