Mujin Wakusei Survive

Synopsis

Outside, the children gather food while avoiding the drones. They discuss how much the area reminds them of their island, and Adam is excited to see a pague, except it's quite small. As the pague returns to its mother, two drones arrive, but someone shoots arrows at them from the bushes and destroys them. In a moment, Howard and Sharla emerge from the bushes. The children have a tearful reunion. Sharla tells the others that when they were sucked down by the quicksand, they fell into flowing water underground. Howard, however, sits in stoic silence. Sharla passes it off as him being tired, and prevents Chako from scanning him. When Luna and Sharla make skin-to-skin contact, Luna feels a weird sensation.

Later, when the children return to finding food, they discover that all the drones have disappeared, which concerns them. They tell Sharla about the hidden room. The pague and his mother return, and Sharla and Howard take him to play with it, but out of everyone's sight, they share sinister glances. They suggest to Adam that he pick flowers for Luna at the end of a tree branch overhanging the lake, but when he climbs the tree, Howard shakes the branch, causing Adam to fall into the water, and then jumps in after him. Adam calls out for Luna, and she, Bell and Howard dive in to save Adam and Howard. When Kaoru reaches Adam, Adam is already sinking, but Luna's power activates, and he starts floating up again.

On the shore, the children are concerned about Howard's listless state, but when Chako tries to scan him again, he knocks her away. In private, Sharla tells Luna he's suffering from post-traumatic stress from being buried in the quicksand, but when they hug, Luna again feels a strange sensation. As the sun sets, the children return to the hidden room, and Sharla and Howard again share sinister glances.
