The jewelry store in Thremten?
Of course it's my thought to get "Jewelry", but I don't think I get the required "Jewelry" that is required to recruit Kurohime.
In fact, out of fun to spend all the unnecessary money I hoarded, I started buying gift items until I couldn't anymore.
I have 999 Jewels, as well as 700 of each Earring and Necklace variation.
So, where can I get that 20 jewelry for Kurohime?
