This people running for their lives in Shibuya crossing amidst a shootout. The camera zooms into Arisu's petrified face as he runs for his life before taking us back to 13 hours earlier, before the chaos. Arisu, Kuina, Chishiya, and Usagi are standing around wondering what the rule of the next game is. But the game only commences when the area fills up with more perplexed players. Suddenly, a sniper starts to shoot the players one after the other. The shooter seems to be using an anti-tank rifle that can penetrate through cars.
