第7話: シモン・スカニアが4年前に姿を消したと判明した後、グループは戻らぬ谷の調査に乗り出す。

Guy informs Toru and his group that the Hero, Simon Scania, was last seen at The Valley of No Return four years previously. However, before they can move on the information, they are ambushed by the Gillett Corps and escape using Fredrika's Dragoon form. Arriving at the valley, they notice it is filled with magic fog. When Chaika starts climbing down the valley wall, the others follow. Unexpectedly, the rock gives way beneath them and they fall into the fog. Akari, Chaika and Frederika, safe in a protective barrier, watch as Toru reacts to an illusion: Frederika was only able to find and catch Chaika and Akari in the fog, thus leaving Toru to suffer from the magic. They wait and eventually Toru stumbles into their barrier, freeing him from the influence of the magic. Reunited, the group makes their way along the valley floor where they find and destroy the machine that is creating the magic fog. With the fog cleared, the group finds Simon, now mad and delusional. Simon reveals that he created the fog machine to force people encountering the fog to experience the betrayal he felt when his wife and best friend betrayed him. After getting Arthur's leg from the machine, the group leaves Simon in peace. (Source: Wikipedia)
