The Keroro Platoon land in Karudopia Kingdom, thanks to one of Kururu's Inventions, and Keroro decides that they should invade the kingdom. However, Kururu's invention has also transported another being: Natsumi Hinata. The Keroro Platoon members scatter, leaving Keroro and Natsumi alone, and Natsumi vows to protect the kingdom from Keroro. Natsumi then turns into a Hunter card. Kururu states that the fact Natsumi joined the game as a hunter card is odd, and Giroro comments that with such a card in hand it might get harder to fight, but they should continue the invasion.
