Depending on the mood of the Golden Chrysanthemums, you might get a variety of "requests":
"Konnichiwa trader. Would it please you to contribute some financial aid to our cause? We would be most grateful. 2 million should suffice, good sir."
"Konnichiwa trader. We would like to impress upon you the urgency of imparting some of your wealth, say 3 mil, to our cause. It could save your life in the quite near future."
"Konnichiwa, gaijin scum. Cut your engines and prepare to be boarded. We're not going to be very nice about this, but you don't have a choice, as we're the ones pointing the guns. Hand over 50% of your cargo or we'll space you and take everything. Accede to our demand and you might just escape out of this alive."
Just a few samples of our demands that we use. Typically we don't pirate unless in groups of at least 2, usually 3.
