You have all been selected amongst the many high school students across the nation to attend a once-in-a-lifetime field trip to Tokyo that promised various opportunities due to the skill sets each of you bring to the nation. Boarding the buses, you notice but a few students you'd recognize from your school, but most of the others are new faces. You'd heard that this trip was to get the brightest or best from many schools, so this isn't a surprise.
You brought some news articles along to read in order to get a better idea what's going on around you. After all, with so much time spent studying and practicing for sports or debate or whatever it is that you have decided to excel in, you figured this might not be a bad time to catch up on what's happening in the real world around you. Since this trip is to discuss your future, you may as well learn about the present first.
(This is the wikipedia article on the movie the game is based on if you are interested)
The trip has been a long one, and at some point you eventually fall asleep due to the time of day. Upon waking up, you find yourselves being herded out of the bus by gunpoint and forced to walk in a straight line. Glancing about you, you do not recognize the place at all and it seems you are being lead into a very old school building that has not likely been used for some time.
After being herded into the school, you notice everyone is being shoved into a single room, handed a book that looks to be an instruction manual and forced into the back of the room. Looking around, you see confusion amongst everyone, but nobody has the courage to speak up at this time. You notice some fellow classmates as well and walk over towards them, quietly asking them if they know what's going on.
Unfortunately, they don't.
As the armed men in the room snap to attention, you see a familiar face walk into the classroom. He was a professor that had traveled to several schools to teach, but after a school incident between him and a student had gained him an early retirement and a brief spotlight in the news, everyone in the room likely knew who he was.
"Welcome Students. My name is Kitano.
You are very lucky because as of today, you will be participating in a game called Phalla Royale. I am here today to tell you I will be monitoring your progress and I will give you the proper instruction and supplies in order to decide your own futures.
You will notice that we've given you some instruction manuals on your way in. I'm going to give you a few minutes to read over those manuals before we start with the next phase of the game. After those few minutes are up, you will each receive a bag that has some food, water, map and another surprise that's random.
The goal here, students, is to tell me which school is better. As you've noticed, we've selected from the very best and brightest amongst a number of schools. You will be given 10 days maximum to determine a winner. If there is no winner by the end of the 10th day, everyone remaining will die by collar detonation."
It is at this time you and the other students realize you are all wearing collars that are tightly strapped to your neck.
"I'd be very careful with those collars if I were you. They are there to provide us with your current location and if necessary, we can also remote detonate those collars.
So, you may start reading your manual now and once your time is up, I will start calling names. Once you hear your name. You will come up to the front of the room, you will be given a bag and you will be sent on your way. You will be escorted out of the school facility and you will not be allowed entry until the game is over, provided you are on the winning team. As each student leaves, there will be a brief break between releasing each of you so you have the chance to get away.
Students. You have 5 minutes to read the manual before I start calling names.
Remember one thing students. Do not disappoint me. That is all."
