Chou Gekijouban Keroro Gunsou - Enshuu Dayo! Zenin Shuugou Japan - NDS - Action

My name is Sergeant Keroro, and I am from Alien Keron. Giroro, who was annoyed at us only building Gundam models, started special training for us... "During the training, we received mysterious communications, were attacked by unknown enemies, and it was all chaos. The communication that was finally deciphered contained further incomprehensible words: "Fragments of an ancient ultimate weapon are about to be resurrected." This is the beginning of the Keroro Platoon's first and last serious operation.
