A living hell for a trapped undercover investigator! For many generations, women have been the breadwinners of the family. Like mantises, they only use males for fertilization, then discard them. Thus, the Daitoro family, a crazy female lineage whose brutal lesbian temper was amplified to the limit. The head of the family, Hana, who owns enormous wealth and lives a luxurious life, and her beloved daughter, Misato. The next prey of the distorted sexual desire that has long been passed down in the bloodline is a female investigator, who single-handedly infiltrates to capture them both!
