Is there a way to join games cross-block?

Can't play with friends due to this xD

Doesn't seem to be; I tried joining a friend by their Arkz Card, and tried joining 'parties with friends' at the Quest Counter and neither worked.

Honestly I think the only solution at this point is to wait until some of the Japanese players go to bed.
