The evil organization "Shadow Ghost" has launched an invasion of Earth from space. Under its top leadership, four legions have been deployed to carry out combat operations across the planet. The Beast Army Legion attempts to track down Saber Beagle, a cyborg who escaped during experimental surgery, but their mission is disrupted by Saber Tackle, another cyborg who also fled during modification. In response, the Beast Army Commander devises a new operation: seize a powerful laser cannon currently under development by a scientist, and orders a high-ranking officer to execute the plan. However, the scheme is thwarted by heroes and heroines. Though the laser cannon unleashes its devastating power, the blast claims the lives of several female combatants. A brutal battle ensues, a desperate fight where lives hang in the balance. [? END]
