"Why have I become a man at the end of the World! I am a woman!"

Elyrion was the chess piece of the Gods, a piece that could be destroyed at any time. After she died in her first life as an Elf Princess, she becomes the puppet under threat that is used to entertain them. After serving for thousands of years, her only wish is to die and free her people from the threat. "If you do not obey, your homeworld and your people on it will be destroyed forever with no right of reincarnation." In the last mission, her role was to find a necklace, give it to the villain protagonist and then die incinerated by his firepower. Why is the necklace different? (...) Overnight after obtaining the necklace, she wakes up inside an uninhabited subway laboratory, the owner of this body died by the Biological Disaster that brings world 'Eba' to its end. The necklace transmits to her the memories, knowledge, and skills of her previous owner and also the memories of the previous owner of the body. A unique space, a survival system, and many more resources. The water became contaminated, the animals and plants mutated into Zombie beasts being poisonous for the consumption of living beings, the human dead rose from their coffins devouring everything in their path, they became Zombies. Supplies are scarcely generating the growth of Zombies, a world known as 'Eba'. The atmosphere is radioactive, sunlight is like lava in the day, the night became colder than the north and south poles, Zombies are immune to the outside. The only survivors isolated under the earth. The change of gender will not be easy for her, adapting to the current situation is better. Creating a base under the earth and creating supply will be the beginning of their survival. Saving the last species of animals and plants will be the second. Saving the last humans will be the third, but... Why is it that there are only women who want to be his wives, small children who call him daddy, and old people who have fallen into madness, who mistake him for their deceased children? What he does not expect is that his new gender would create a great change to his personality, calmly... "I'm not a pervert!, ¡I'm not a pervert!" "Why have I become a man at the end of the World! I am a woman!"
