The Bat Rangers who had infiltrated deep into the Death God Empire suddenly vanished without a trace. The Defense Organization must act immediately, or there's a real possibility they'll be completely wiped out. However, under the current structure of the Defense Organization, there is still no individual possessing the hyper potential required to single-handedly storm the Death God Empire's stronghold. Amid this crisis, the only hope that emerges is Sakiko Mihara—the former Bat Ranger Pink—who retired from duty two decades ago to marry and build a peaceful family life. Answering the Defense Organization's urgent call, she agrees without hesitation, and after twenty years, Bat Ranger Pink returns to the battlefield. But the Death God Empire acts faster than anticipated, launching a sudden surprise attack on the Defense Organization's headquarters. Pink is captured and taken by the Empire, where her mature, voluptuous body is subjected to countless degradations—erogenous zones of her womanhood ruthlessly exploited in ways beyond description. Mimicking the fighting stance of her fellow soldiers, Pink struggles to endure, but the twenty-year gap leaves her severely disadvantaged. Ultimately, she collapses once more, overwhelmed by unbearable pleasure, surrendering completely as she transforms into a shameless, lustful female who greedily devours a man's cock. [BAD END]
