The chapter opens with a chirp from the stage. It's the morning of the big day, and the students are all excited. Everyone's excited because they're going to be playing a game called "bullet train." They're also excited because their teacher has to go early to get the guidebook for the game, which he's been preparing for the last two days. Everyone is excited because it's their birthday, and they all have pillows to sleep on. Everyone wants to go to bed, but they can't sleep without their own pillows. The teacher asks everyone if they have pillows, and everyone says they do, except for the teacher, who doesn't have pillows of his own. He's 33, so he has to sleep without his own pillows, which is kind of weird. Everyone has pillows, but the teacher asks them if they've slept on them before. Everyone agrees that they do have pillows. They've been sleeping on them all night, and now they want to go play the game. Everyone starts talking about how fun it will be to play a game like this, and then they all start complaining about how noisy the other groups are. They don't know how to lead their groups, so they just have to pretend like they have twins. Everyone complains about how hard it is to get to class, and how boring it is. Everyone says they just had a little rice ball, and that's when they realized they'd be playing the same game as everyone else. Everyone asks if they can spend the day with them, and if the teacher won't say no, they can ask him to join them.
