Keroro Gunsou Movie 6: Fukkatsu shite Sokkou Chikyuu Metsubou no Kiki de Arimasu!

The Keroro Platoon has settled into such lazy days that its members hardly resemble invaders planning to conquer Earth. That changes when bizarre phenomena begin erupting across Japan and mysterious symbols repeatedly appear wherever they investigate, leaving Keroro and the others with a crisis they cannot postpone until tomorrow.

Determined to act with at least a little pride as would-be conquerors, the platoon rises to face the threat, only to discover that the danger is growing fast enough to place Earth itself at risk. Between their familiar chaos and a battle larger than anything they have faced before, they must uncover the meaning of the strange signs before their comeback becomes the planet's final disaster.
