The episode starts with Tomosu Hinohara standing alone on a beach and looking up at the sky. A large ship is than seen in outer space as the Keroro Platoon look in awe. Later Fuyuki is seen hanging out with Tomosu, Fuyuki appears surprised that Tomosu is into Paranormal stuff and is the head of the Occult Club. Fuyuki instantly likes him, however when they are talking a weird voice comes in. And Fuyuki is frightened as a girl named Myou Kaneami introduces herself, while she predicts an aliens's landing. As Myou predicted the same ship the Keroro Platoon saw lands in The Hinata's backyard, scaring Natsumi. Meanwhile inside the Keroro Platoon's base, the alien breaths in, as the Keroro Platoon think he's about to attack, until the alien know as Shin Keroro sneezes, making the platoon fall over. He questions where he came from and how he ended up in the Keroro Platoon's Base, Keroro answering. Shin instantly goes back through the hole he made, as Tomosu is seen climbing into said hole. However, Shin flies up into the sky taking Tomosu with him. Shin introduces himself to Tomosu and says that he is his friend, confusing Tomosu even more. Meanwhile everyone else is looking in shock (Except Myou and Kururu). Later, on the beach we saw earlier Tomosu is still standing there this time with Shin Keroro. Shin asks if they will go on many adventures together on Pekopon, Tomosu answering yes.
