Rockman X DiVE is a pretty big hit in Asia. So much so that it's dominance has bled into LINE with the release of brand-new stickers! They're cute, fun to collect and... they're only available in Taiwan, Hong Kong and Macau.
But hey, the good news is there are different methods to legitimately download out-of-region LINE content. A little Googling can go a long way. But for now you can see what all 40 character stickers look like here. There's one for X, Axl, Zero... even RiCO and ViA (who apparently has a mouth? Neat, I guess.)
If you have the means to do so, you can download the stickers here. And, no; I don't have any updates on when X DiVE will become available in the states. Sorry, folks!
