>>91850053last year they carved out a huge block for zaiko (something like 10% of the tickets i think). kaigainikki on average spend 3x more on merch so they will bend over for us.
there are also not many people willing to pay thousands to visit japan so the odds are fairly good.
if not, you can almost always find a reseller on discord who won something they didn't want or need and can exchange wristbands with you since they will be there the same day for something else.
good luck!
