Mujin Wakusei Survive EP18 - This is the Eastern Forest!?

Shingo, impatient with the delay in plans to investigate the ruins, sneaks out early one morning, talking Howard into coming with him, and Howard kidnaps Chako without Shingo's knowledge. When the other children wake up and find them missing, Luna, Bell and Menori follow. In the forest, Chako and Shingo are fascinated by the fact that gravity seems lower. Both groups find themselves lost and walking in circles. Chako, Shingo and Howard find a giant tobihane, dead, and are subsequently chased by the giant Tasmanian-devil-like predator that killed it. They run into Luna, Bell and Menori, and the six of them flee together. The mysterious voice tells Luna to jump over a cliff to escape, and when the children do so, they disappear half-way down and find themselves in front of the ruins. They realise the forest they were lost in was some sort of illusion. The giant crustacean appears again, but in a reflex, Luna tells it to stop in her mind, and it does. They approach the door of the ruins, and when Luna places her hand against it, the ruins glow pink and the door opens. The children enter, finding a small alien boy in a cold-sleep capsule inside.
