I had a brilliant Idea for the Japan plotline!
We walk into a Nightclub, where we have to assassinate a VIP, before he can spread it to others, Including the emperor, and several other politicians. I set up my sniping position, and then, BOOM! something goes wrong. But We have to contact the American CDC to explain, and the UN, We could have some scenes where we get drunk on Sake, or a girl tries to seduce someone in the squad or something. And when we get caught, we have some witty banter with the police who don't understand English.
