Ep. 19: Sophie meets Zeringer while Yukina escapes captivity and Muetta prepares to pilot Kuromukuro

The Cactus unit returns to the space station with Yukina, whom the Efy Dolgh believe is Muetta. At the UN, Dr. Hausen reveals that Yukina and Muetta share identical DNA, concluding Yukina was taken by mistake. The UN discusses a rescue mission but reaches no decision. Meanwhile, Sophie encounters mysterious writing asking if she wants to learn the truth about demons. She agrees, and upon returning home, she meets a Demon who introduces himself as Zeringer Mundef Bischrei, stating he is an enemy of the Efy Dolgh. Kennosuke asks Muetta (Yukihime) to pilot the Kuromukuro with him. She agrees to assist in reaching the space station but cannot guarantee his safe return. As they prepare to depart, they view a recorded message from Princess Yukihime urging her ancestors to fight demons and protect the Washiba Clan. Muetta wonders about unknown aspects of her past. On the space station, Yukina escapes captivity and realizes she is no longer on Earth.
