Save the Humans ArcEdit

Rubero is the head of one of the groups instructed to take care of the towers constructed by the humans. Kenros and Rubero each find a tower. Unfortunately just as they are about to blast into the tower, the humans attack.[3]

Before the tower destruction group could finish the prototypes, the prototypes retreat. Outside the cave, there are thousands of prototypes waiting.

The tower destruction group is chased down by the prototypes. They attempt to retreat to the cave, but the prototypes manage to wall it off before they can. Eventually, the prototypes surround the tower destruction group. However, they are saved by reinforcements provided by Shin.[4]
