In the past it was kinda easy to guess or call the upcoming setting... but since EDF and with Prison... those were literally unexpected and makes it even harder to think about it.
Sure the Passionate Teacher, was kinda off.. they should have named it something like "Back to the Past" and put them into a time traveler suit instead.
The most named ones are still Fireman & Army
I am sure, they will keep the Bus at start and also a the second rest room setup, if needed or if possible.
The don't get sacred part, will stay anyway.
But we will never really know, until it is out.. Maybe they actually surprise all with a totally new way.
If we go based on the most Popular Jobs atm there....
teacher
police officer
doctor
lawyer
salaried worker
writer
politician
civil service
engineer
actor
scientist
florist
chef
Highlight the red ones, which would work for them perfectly, also for famous cameo..
Totally can see them in a Actor School/Uni setup or general Movie related, such as Hollywood, just the Japanese version.
same with being lawyer... chono appears as judge
since they are also doing alot food related.. chef would be a good setting too for them.
