Sailor Athena, a warrior who has protected Earth as a member of the Sailor Soldiers, faces off against the strongest and most vicious, depraved demons to arrive from outer space. These demonic sorcerers attack the lovely and beautiful fighter Sailor Athena in order to steal the sacred power of the Sailor Soldiers for themselves. However, Sailor Athena possesses strength and beauty far surpassing the demons' expectations, gaining the upper hand in battle. But the sudden appearance of the monster Scorpio from the constellation Scorpius completely turns the tide. Overpowered by overwhelming numbers, Sailor Athena is forcibly pinned down, collapsing to the ground with a face twisted in agony. Her pitiful state stands in stark contrast to the majestic, divine image of a Sailor Soldier.
