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.
I bet that goddamn slut put him up to it.

Aposto que aquela piriguete que fez isso.
Готов поспорить, Шлюха подсказала.
