Agent Fumika, a beautiful and highly skilled detective trained from childhood in combat and infiltration techniques, has always prided herself on perfection and excellence. However, betrayed by a trusted junior partner, she finds herself trapped in the very nightmare she feared most during an undercover mission. After each sexual assault, a special spray erases her memory completely, wiping everything clean every hour. Again and again, she is forced into a relentless cycle of infiltration, betrayal, and brutal humiliation. Unaware of how many times she's been violated, her body gradually becomes addicted to pleasure while her mind slowly shatters. Upon discovering the truth about the memory manipulation, her once-unbreakable pride is utterly destroyed. Finally surrendering, she whispers, "Just make me forget everything..." as she fully descends into becoming a submissive sex slave.
