Guy informs Toru and his group that the next Hero they can find, Simon Scania, was last seen at The Valley of No Return four years ago. However, they are ambushed by the Gillette Corps before escaping using Fredrika's Dragon form. Arriving at the valley, they noticed a fog made by magic in the valley before Toru, Akari, Chaika and Fredrika accidentally falling in. In the fogged valley, Akari, Chaika and Fredrika, in a protective barrier, notices the fog causes illusions which Toru believes he and Chaika survive the fall and became a couple only for Gillette to take her away. The trio manages to drag Toru into the barrier, where they decide to destroy the machine that makes the magic fog. Using Chaika's magic to temporarily dispel the fog, the group manages to find and destroy the machine. With the fog cleared, the group finds Simon, now mad and delusional. Simon reveals he created the fog machine in revenge when his wife and his best friend betrayed him in order to show anyone going into the fog the pain of being betrayed by a loved one. After getting Arthur's leg from the machine, the group leaves Simon behind while the girls question Toru on his illusion.
