In the Program[]

When Makoto Hashimoto's group (consisting of herself, Suzuko Arikawa, Fumiya Daichi, Yuki Ito, and Hajime Minami) were allowed to stay in the school while the rest of the class was forced to live in hellish conditions, the other students began to resent them, Masako included. Masako snuck onto the school grounds to talk to Yuki, but was discovered by Miwa Nakaya who killed her by activating her collar.
