Ep. 7: The group investigates the Valley of No Return after learning Simon Scania vanished there four years ago.

Guy reveals that Hero Simon Scania disappeared at The Valley of No Return four years ago. Before the group can act, the Gillett Corps ambushes them, forcing an escape via Fredrika's Dragoon form. Upon reaching the valley, they encounter dense magic fog. When Chaika descends the wall, the others follow, but the ground collapses, dropping them into the mist. Inside a protective barrier, Akari, Chaika, and Frederika observe Toru suffering from an illusion caused by the fog. Frederika explains she could only shield them, leaving Toru exposed. Toru eventually stumbles into their barrier, breaking the spell. The reunited party locates and destroys the fog-generating machine. They discover Simon, who is now insane and delusional. He confesses to building the device to inflict the betrayal he felt when his wife and best friend abandoned him. After retrieving Arthur's leg from the machine, the group departs, leaving Simon alone.
