The Earth Defense Force defeated their archenemy Gozua, but the cost was devastating. Their base was completely destroyed, leaving only one survivor: Mermaid = Aoi Nanami. Though she miraculously survived near-fatal injuries, a new threat immediately emerged. Alarms blare as remnants of Gozua launch a surprise attack, leaving Nanami isolated and surrounded. Transforming into an incomplete Mermaid form, she faces off against the evil space beast warriors but is gradually overwhelmed. Her damaged suit is stripped away, leaving her exposed and helpless as she continues to fight. Eventually, all hope of victory vanishes and her spirit nears its breaking point. Yet the fire of determination in her heart refuses to die. "I am... Chargemermaid... I absolutely... cannot lose!!" These words mark the final outcome. [BAD END]
