Ep. 4: Students explore the newly opened second floor facilities under Monokuma's strict time limit.
Aired on July 26, 2013

The second floor, including the pool and locker rooms, has opened for the students. Monokuma allows them a few days to explore the new area before he loses interest. However, he imposes a strict deadline of 24 hours for the students to kill someone. If they fail to commit murder within this timeframe, Monokuma threatens to broadcast their darkest or most embarrassing secrets to everyone. This ultimatum forces the group to navigate the new environment while facing the pressure of potential exposure and the requirement to eliminate a peer within the specified period.
