did they pay their way to S-rank or what, why are you guy so weak, even if that slime immune to normal damage, you don't just "we can't use fire because we are in the forest" and just gave up.
or why even taking on quest that clearly again you?
1-2 shota lovers and a secret lesbian. Hardly a normal party and prime suspects for any kidnappings.
For an S-rank party they had a hard time with that slime. The monk should've at least avoided getting caught. I'm sure Arian is just horny by this point. It would've been faster for lark to imbue the archer's arrows with fire. Also funny that the mage only knows Megumin style fire magic.
