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.
The monster crest and magic outfit 
add up to 340 silvers in total.
شارة الوحش وزيّ السّحر يجعلان الفاتورة
الإجماليّة 340 فضّية
Das Monstersiegel und deine
magische Kleidung haben mich
Entre la marca de monstruo y la ropa
mágica gasté 340 monedas de plata.
Entre la marca de monstruo y la ropa
mágica gasté 340 monedas de plata.
Entre le sceau de contrôle
et ta tenue magique,
Tra il sigillo da mostro e l'abito magico
mi sei costata 340 monete d'argento.
Com a maldição e esta roupa,
totalizamos 340 moedas de prata.
Клеймение вкупе с волшебной одёжкой тянут…
на триста сорок серебряных.
