Keroro Gunsou Movie 4: Gekishin Dragon Warriors de Arimasu!

Life continues as normal on Earth... except for the fact that strange giant arches have appeared across the globe! While Keroro remains at the Hinata residence and terrorizes Natsumi on a daily basis, the rest of the platoon has gone to investigate the mysterious phenomena. With Tamama enjoying the food in France, Giroro stationed in New York, Kururu based in Australia and Dororo camped out in Africa, it seems that the Keroro shoutai have everything under control. However, when most of the squad are mysteriously transformed into Dragon Warriors, it’s up to Keroro and the Hinatas to find out what’s going on, uncover the mystery of the arches, and discover a way to return the rest of the gang to normal.
