A helicopter is flying over Racoon Forest as someone speaks about the events:

*Keroro: K. Platoon is flying around the forest zone, situated in northwest Raccoon City (Yes, a city was created while we were on... Oh, nothing important), where we are searching for the helicopter of our compatriots, G. team, who disappeared during the middle of their mission. This time, we were with REAL guns and with REAL ammo (and so, with real equipment too), that thing was serious. Actually someone was missing in our group during the assignment of this mission, so the army hired two "new members", one guy named Daruru (the captain of our mission. He is familiar to me, I don't know why...) and a little soldier named Jonunu.*

Kururu: Keroro, you haven't found it yet? "Huhuhu?"

Keroro: No, not yet, Kururu.

*Keroro: Bizarre murder cases have recently occurred in Raccoon City. There are outlandish reports of families being attacked by a group of about 10 people.

Victims were apparently eaten.*

The helicopter is now on ground as the team investigates the area.

*Keroro: The G. Platoon was sent in to investigate, but we lost contact (that's ironic, in a way).*

The helicopter's searchlight plays over the forest. But something catches the private's eyes: a ruined helicopter among the trees.

Tamama: Look, Keroro!

The helicopter is wrecked; Jonono breaks open the door, and he see that the side-window is broken. There's also a hole in the main windshield.

*Keroro: G. Team's helicopter was a derelict.*

Jonono looks around the front of the helicopter... But that, he sees than that thing is empty, nothing was here... He returns with the group.

Daruru is walking around the woods, holding his pistol at ready over his other arm, which is holding a flashlight. Giroro, behind him, and Keroro, across from him, do the same.

*Keroro: We continued our search for the other members... And it turned into... A nightmare...*

Someone appears to be rotating around the members of the team, watching them...

We then switch to Jonono's headcamera view. He is breathing heavily. He then see Tamama in front of him, walking towards the camera. Jonono turns around and investigates something by the tree behind him... He walks cautiously towards it and hears a growl. It was like a dog's one. He panics and looks around, his shotgun at ready.

After a few silent moments, he decides he's fine and lets out a sigh of relief. But just as he put his gun down, something bares its fangs and jumps atop him. A shotgun blast is heard, and all the K. members turn and look in its direction. He is devoured alive by the mutant dogs. A splotch of blood makes its way onto the soldier's camera...

All this time, Tamama has been shooting at the dogs as well. His pistol is empty, but he keeps on pulling the trigger as he stares at the spectacle before him.

Suddently, one of the dogs, still chewing Jonono's flesh in its mouth, turns around and notices Tamama. He staggers back slowly and falls while the dog jumps at him. Luckily, Keroro guns it down, leaving the surprised private with a spot of blood on his face.

Keroro: Come on!

He takes hold of Tamama and runs just as the other dogs notice what's

going on. As the pair runs, they look up and notice the helicopter flying away.

Keroro: Hey! Kururu! Where the hell's he going?

The dogs seem to be catching up now, and the sergeant turns to brace himself for the impact of a dog jumping at him. A gunshot rings through the air, bringing down the creature.

Daruru: Keroro, this way!

Keroro and Tamama run past Daruru, as the team leader fires three rounds at the dogs. Giroro is firing too, with his mighty new Colt Python at the dogs. He fires off three shots; the second one hits a dog, instantly killing it. They all run towards the house, and Keroro, Daruru and Giroro each fire one more shot at the dogs.

Giroro: Dammit!

Keroro: Make for that mansion!

Eventually, they have made it. The survivors enter the mansion, unsure of what will happen next...
