So, you have two shows that you really want to Crossover, but there's a problem: they live halfway around the world from each other. What to do?
A common solution is for the characters of one work to visit the city where another work is set for some leisure time (for example, vacation, concert, sporting event, movie premiere), and just happen to run into each other. Characters from one series explicitly summoning or sending for characters in another do not count.
See also In the Past, Everyone Will Be Famous for when time-traveling vacationists just happen to run into historical figures.
