Aoi Tsubasa, female leader of the Aoi clan and commander of a ninja group, is rescued by Redwing just moments before being brutally murdered by the witch Gorgon, who annihilated her entire clan. Recognizing Tsubasa's extraordinary abilities, Redwing recruits her into Wing Force. As Bluewing, she resolves to fight against the alien armada Vailers' invasion of Earth. Grieving the loss of her people and determined to protect the Earth she once loved, she faces Baravile, Vailers' strongest monster. Overwhelmed by an enemy unlike any she has faced, Bluewing is gradually driven into desperation. When Bluewing attempts a counterattack, Baravile injures her body and, enraged, captures and tortures her. As the half-conscious Bluewing continues to be assaulted, Vailers' commander Radarg joins in. Tormented relentlessly, Bluewing finally loses consciousness. Forced into a situation where she must endure extreme torture, she defiantly refuses to surrender Wing Force's secrets to Radarg. Enraged, Radarg subjects Bluewing to a cleansing machine before bringing her before Redwing. Bluewing raises her gun at Red. But will she be able to endure the hell that awaits her? [BAD END]
