Rin can also teleport. However, I would assume they have magical detectors in place to prevent this or other similar magical occurences from happening.
That's assuming they know what a teleportation spell is. There mustn't be too many mages able to cast it, and the ones who do (archmages, really) probably aren't interested in stealing ore from miners.
Considering there's an Adventurer's Guild branch here, the chances of finding such dungeon have increased.
I have a feeling that the branches of Adventurer's Guild are everywhere, for even peasants and kids to be aware of their prices. They are probably the KFC of fast-job networks. They must have offices in every major city.
I would hardly call it a unique opportunity. If anything, this is presented as an option to dig information on the city.
That reminds me: has the Google Translator spell been improved to the point that Erd can read text?
That shouldn't be a problem since it has been confiormed the kids can read.
Lastly, how long would we stay in this town if C wins?
No longer than in other instances, I imagine. We aren't trying to marry his daughter, or, God forbid, teach her. She isn't even really the point. We are trying to get a closer look at people running the city. There might be some dirty underwear for us to exploit.
If all else fails, we'll just have bandits/armored Rin kidnap the damsel and offer our services to rescue her, earning our 'in'.
This is a region in which slavery is accepted, so the probability of finding monster-girls for sale at Yuria is quite high.
I really hope so, or we will have to make our own slavegirls, which would be a major pain.
But really, we should look into making our white-knighting profitable by saving all the pretty maidens from the bandit clutches for a reasonable fee. Naturally, we will offer a variety of payment methods.
