Guardians of Stone

"'On a rugged path leading him to Haru, Akiyuki meets a rugged father and child devoted to a rock. Next episode, Guardians of Stone. Humanforms just won't leave Xam'd alone!' - Akushiba, narrating the preview for the episode"

Summary
Haru, Furuichi, and their squadron are assigned to engage the rogue Xam'd in battle, but Haru realizes that it is pregnant before the squadron has it constrained. Akiyuki receives Haru's stack of letters and learns that she will be waiting for him at Tsumebara Pass on the island. Nakiami allows him to go there, under the condition of bringing along a pet nekomata, not knowing it has a tracking device on its collar. Kagisu orders Haru and Furuichi to go Tsumebara Pass with their group to locate a squadron that has gone missing. In the mountains, Akiyuki, after encountering a man who turns into a Humanform, is saved by Kio and Zuizo. They tell him that more and more people have been turning into Humanforms since the air raid a month ago. Worried about Akiyuki, Nakiami leaves the airship to go look for him in the mountains.
