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 only I could use support 
magic right now...
...لو أستطيع فقط استخدام سحر الدّعم الآن
Wenn ich jetzt nur Unterstützungsmagie
verwenden könnte …
Si pudiera usar magia de protección…
Si pudiera usar magia de protección…
Si seulement je pouvais utiliser
des sorts de protection…
Se solo potessi usare
degli incantesimi di supporto...
Se eu ao menos conseguisse
usar magia de suporte...
Если б только…
я знал заклинания поддержки.
