GRET-51 Giant Heroine Hyper Mummy Shirasaki Mizuki

Ann is an alien. Yes, she is the giant of justice, Hyper Mummy. She hides her alien identity and lives on Earth as a member of the Space Defense Force. One day, a series of disappearances of young women occur. The only clue they manage to obtain is that all the victims were wearing the same brooch. Ann, who has a brooch in mind, visits a friend. However, the person who appears is an alien who has been driven from their home planet. This alien feeds on human b** and eggs, and because the female population has become extinct, they abduct human women and use them as vessels to increase their species! [BAD END]
