Okay, so... the challenge:
With no ASB, or failing that, as little ASB as possible, get the Teutonic Order to Hokkaido before 1467 and install them as the local rulers. The overall ideology should be similar to OTL, but they can be changed a bit by circumstance and necessity.
Tl;Dr: The only limits are that it has to be before 1467 and that the Teutonic Knights need to still be recognizable upon arrival and then afterwards.
Have fun!
