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 you won't listen to me, 
then I don't need you anymore.
إن كنتِ لا تصغين إليّ فلستُ بحاجة
إليكِ بعد الآن
Se continui a disobbedirmi in questo modo,
non avrò più bisogno di te.
Se não vai me ouvir,
não preciso mais de você.
Если не собираешься меня слушать…
катись на все четыре стороны.
