The invasion of Earth by the Metallicans has finally begun. Cities across the planet are being destroyed one after another, and the Earth Defense Force has suffered devastating losses. Humanity's last hope rests on a single warrior—Cosplayer. [1] In battle against enemy soldiers, Cosplayer powerfully defeats them one by one. [2] Next, facing the enemy Iron Gill, after a fierce back-and-forth struggle, Cosplayer is captured. Choked by chains and tormented by a terrifying electromagnetic whip, she endures intense suffering. [3] Though she defeats Iron Gill, a new powerful foe appears—Gyras, a cyborg from the Metallika star. He unleashes a relentless barrage of body blows. Cosplayer is forced to swallow Gyras's oil, subjected to brutal striking attacks, and continues fighting through agony. [4] As part of Gyras's strategy, Cosplayer is restrained in a lewd position and broadcast to all of Earth. Witnessing her helpless state, humanity begins to lose the will to fight. [5] She is then doused with a special conductive solution that heightens electrical sensitivity, electrocuted, and ultimately killed. [6] Using her lifeless body, Gyras further crushes Earth's resistance.
