Basking in its newfound powers the Eroder attacks and Sarah and Noctis fight it off together. The aliens remove the magic barriers for Sarah and Noctis to proceed to the coliseum, where the Eroder abandons its Hiso Alien form to copy Sarah's powers. The Elder asks them to save the alien society from the Eroder, and the two agree to it, as if the Eroder is left to run amok, it would only be the matter of time until it could appear in their worlds as well. On their way to meet the Elder, a tree comes alive and starts to attack, but Sarah saves Noctis from it and he again heals her with a potion. He scolds Sarah for being so reckless, and she thanks him for his help. Noctis catches them midair and warps them to safety. Sarah rushes after the kids and gets the phone back, but when she helps an alien child hanging precariously over a waterfall, the tree they were on snaps. They follow the alien to its village where a group of alien children steals Noctis's smartphone, impressed they have met a real prince. The two combine their skills to fight them off and learn to fight well together. Sarah and Noctis follow the alien and find statues coming alive to attack them. Sarah and Noctis have been summoned to the forest by the Great Tree at the behest of the Hiso Aliens' elder who wants two saviors from other worlds to save them from a monster known as the Eroder who has been eroding their world. They meet a small white alien who explains the situation to the pair, although only Sarah can understand its language. Sarah asks for him to partner up with her to solve the mystery, and though Noctis is reluctant, the two explore the mystical forest ruins and discover the area is sealed off by magical barriers. She is thankful, but Noctis remains distrustful. She is hurt and Noctis heals her with a potion. Noctis is whisked away to the mysterious world of Hiso Aliens where he meets Sarah.
