Alien Byuyo discovers the true identity of Omega Lady as Sakura Oshiro and subjects her to torture, conducting grotesque human experiments to uncover her weaknesses. Learning that Omega Lady is vulnerable to cold, Byuyo deliberately releases Sakura to crush humanity's hope, summoning the snow beast Snogiran to wreak havoc. Sakura transforms into Omega Lady to fight back but struggles against Snogiran's icy powers. Though she finally defeats Snogiran, Byuyo reappears in the opening and overpowers her once again. Byuyo immobilizes the helpless Omega Lady with intense cold and proceeds to saw off her limbs with a hacksaw. As Byuyo gazes upon the dismembered heroine, he declares victory over mankind—until suddenly a beam of light descends from space, reviving Omega Lady. The resurrected warrior overwhelms Byuyo, but at the final moment, she clutches her womb in agony and collapses.
