The remaining 10 students are given an order to race to Mt. Nuegakubi, where every 8 hours the person farthest away gets punished. While Natsuko leaves everyone behind in the dust, Nobuaki repeatedly goes out of his way to help his classmates who are falling behind, despite them insisting multiple times that they don't need to be saved, insisting he could not bear to see anyone die anymore. His efforts winds him up amongst the students in last place, with Riona who lacks stamina and Masatoshi who got shoved down a flight of stairs by classmate Takuya. He also appears to have pushed himself to the limit as he begins to hallucinate. As they are running along the ocean, Masatoshi suddenly jumps in the water. Nobuaki follows to save him but fails to do so and Masatoshi drowns. Riona then warms him up and Nobuaki regains his resolve to continue. As the 8-hour mark is imminent, Nobuaki deliberately stops to tie his shoelace, just as a death punishment text gets sent.
- It is revealed that there are 9 survivors left.
