As the girls debate going on a trip together before Saki moves, Natsumi suggests they go to Shimada. As the girls prepare for the trip, Saki has a nightmare about being left behind by the others. The day of the trip comes and the girls soon arrive in Tokyo and spend the night on a ferry. As Saki once again experiences the same nightmare, Natsumi tries to get her to be more honest about her feelings. Upon arriving in Shimada, Yuka almost drowns in the sea but is rescued by a lifeguard who seems agnostic towards the girls.
