The dark empire Dargot devises a plan not to destroy the Sailor Warriors, but to brainwash them into joining their forces. In this process, they capture Sailor Medium—the warrior who wields intelligence and water as her weapons—and attempt to convert her. However, she stays one step ahead. Learning of her resistance, Dargot summons Ragmiedender, their strongest dark monster, to stop her. Ragmiedender uses its tentacles like whips, brutally overpowering Sailor Medium. It steals energy from her crystal, then uses its horrifying abilities to corrupt that energy into evil power and inject it back into her. This is done through an unnatural method: inserting a reproductive tentacle into Sailor Medium’s most intimate areas and pumping the corrupted energy in and out. Even as she is violated, Sailor Medium is forced to de-transform, then transformed once more into a Sailor Warrior—but now, evil thoughts are implanted deep into her mind, gradually twisting her heart beyond recognition.
