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.
But I guess you can't have her walking 
around in public looking like that.
لكن أعتقد أنّكم لا تستطيعون جعلها
تمشي أمام العلن بهذا الشّكل
Aber in der Aufmachung können wir
sie trotzdem nicht rumlaufen lassen.
Aunque no puedes llevarla así.
Toma, otro cliente lo dejó tirado.
Aunque no puedes llevarla así.
Toma, se lo dejó otro cliente.
Mais bon, elle peut pas
se promener en ville comme ça…
Tuttavia, girare conciati così
potrebbe crearvi dei problemi.
Mas não dá pra ela ficar
andando assim na cidade, né?
Правда, в таком виде расхаживать
плохая идея…
