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'm no savior, and I need to 
act in my best interests.
لستُ منقذاً، وعليّ أن أتصرّف بما يخدم مصالحي
Ich bin kein Heiliger. Und Gefahren
schafft man besser frühzeitig aus dem Weg.
No soy un santo y es natural
querer evitar problemas.
No soy un santo,
y es natural querer evitar problemas.
Je suis pas un saint, et c’est normal
de se débarrasser des nuisibles.
Non sono un santo, inoltre è normale
che voglia difendere i miei interessi.
Não sou salvador e eu ajo
conforme meus interesses.
Так я и не святой,
а бешеных псов надо истреблять.
