Plot
As Mob, Takenaka, and the Telepathy Club members are driven through Mt. Mudboat by Reigen, it's learned they missed their turn miles back and to make matters worse Reigen hits a tree. Reigen decides it's best to return to the hiking trail, but Saruta has to take a pee. So, Reigen has Mob follow him, but after a while, they don't return, prompting the group to search for Mob and Saruta; however, the group becomes lost in the woods after they find them. Hence Reigen suggests they head to the mountain's top, despite Mameta forgetting a book with the special spell for summoning aliens written in it. Pressing onward, the group finds a mountain trail, but Tome has a meltdown and refuses to continue any further, but a kind gesture from Mob motivates her to continue.

Eventually, they reach the mountaintop where Takenaka performs the Alien Summoning ritual after memorizing it all night. Tome then motivates everyone, excluding Reigen, to perform the spell too. Soon though, Takenaka reveals that the book's author was arrested two years ago for fraud surrounding the book's authenticity. Despite his confession, Reigen then speaks favorably of Takenaka's honesty, and Tome concurs. As nightfall settles, Reigen suggests they head down the mountain, but Mob insists they contact aliens their own way and succeed in summoning an alien ship. Three aliens beam down to the ground, and after a brief interaction with Tome, they beam them into their ship to showcase it.

The alien's ship interior is oddly similar to the Telepathic club's room, and the group showed the aliens various earth games and pass times. When it's time to go, the aliens give Tome a gem as a gift; hence they all give the aliens a single personal belonging of theirs as thanks, aside from Mob, who demonstrates powers for them. Upon returning to earth, the group relishes their adventure, but learns that Mameta was left behind. He eventually returns to earth after convincing the aliens to do so.
