The entire crew is still reeling from the effects of last night's strange dream. Just as things couldn’t get more uncomfortable, the ship is attacked again… from the inside.

With Koharu still missing, Kakeru returns to the surface to find her and his father. Meanwhile, Akito and Nanami prepare to reveal their secret to a member of the ship.

Following Sakuya’s vision of the near future, the crew hurries to rescue Koharu and Mikoto. On the island, Kakeru runs into Natsuhiko and Ron.

The group is finally reunited aboard the ship. The Reset weighs heavily on their minds, and Koharu fears the inevitable global consequences of their decision.
