Jin actually has a few arcs. First was her original trip around Sinnoh as a teenager that was basically her being pulled into the plot of Platinum. Her next big arc was her finishing her aura guardian training in Kalos where she not only got her mega keystone, met her Riolu, but also was the first time she fell in love…and subsequently was the first time she got her heart broken. Then there was her trip to Hoenn and her meeting Mary…you can tell how that went. And while there are a lot more I could get into, the last one I want to mention is her becoming the warden to Regidrago and that involved a trip into the Crown tundra along with Mary and their daughter.
