Sgt. Frog

In the year 1999, planet Earth found itself under attack by aliens... or it did in the dreams of paranormal enthusiast Fuyuki Hinata, at least. But when his fierce-tempered older sister Natsumi jokingly pointed at the wall and said 'Look! It's a real, live alien!' little did she know that Sgt. Keroro of Planet Keron's invasion force had selected that exact spot as a hiding place! With his cover now blown, the Sgt. is forced into doing chores for the Hinata household, while he attempts to re-establish communications with the rest of his platoon and devise plans for world domination!
