You, Nagito, Chiaki, Nekomaru, Gundham, Hajime, Fuyuhiko, Akane, Kazuichi and Sonia were exploring the fourth island until Monokuma told you that you all have to ride the rollercoaster to receive a surprise. So everyone was discussing whether or not it's a good idea, tho Kazuichi mostly refuses because he's scared, and Nagito seems the most enthusiastic of the group.
