This is only the second time I've ever come across the paw-fetish. The other time was the famous guy on Miiverse/Miitomo who was obsessed with Lucario('s paws).
@Doomer In the beginning, I think it mentioned that he was acting as a trader and had been going back and forth between world for some time and had obtained (pre-city purchase) nearly 30 gold coins. Gold is gold so long as your modern-era buyer doesn't care where you got it from.
From here, I'm guessing the story goes something like:
-game releases
-devs realize that Summoners are actually really OP if played right
-too late to patch, so try and stunt early growth to dissuade people from choosing it
-MC doesn't care cause not a minmaxer
-becomes OP by being a casual...
It looked like it was going okay, but then that got very rapey very fast.
And of course she's going to "realize her foolishness and fall for him in the end" because that's just the kind of manga this is.
