Saber Five's Red Ace, Ken Haruka, known for her exceptional combat prowess, often fought alone, diverging from Saber Five's core principle of teamwork. Targeting Haruka, Quaol, a high-ranking officer of the evil alien Garon Empire, deploys Exa, an advanced robot designed to analyze Saber Five's capabilities. Equipped with superior combat strength and torture functions, Exa is engineered to dominate enemies completely. Remaining vigilant, Haruka is nonetheless unexpectedly pierced by Exa's venomous needle and captured. She is exposed to a scanning beam meant to analyze her powered suit, but sensing its danger, she endures intense pain to deactivate her transformation. Quaol torments her, demanding she transform again, but Haruka resists until she finally loses consciousness. This decision seals her fate in tragedy. [BAD END]
