About the Savior Turning into a Girl

(Let us make it clear that the protagonist will completely become a woman, and at a crucial salvation node ahead, she will accept a new identity.) I saved the world... But not completely. In order to continue to protect the world, I hid my identity as the savior and used my superpower to become a woman. Unfortunately, because I became too beautiful, my handsome colleague fell in love with me... The black dark energy from outside the Milky Way washed away the blue planet where humans live, wiped out most of life, and brought terrifying alien beasts. It also gave humans the power to awaken superpowers. When the world was destroyed, someone awakened the highest level of superpower, created a mirror world, and transferred monsters and disasters to a world he called the Mirror Realm. The battle between humans and alien beasts is far from over. Although this is a game, it is not a joke! The mirror world that overlaps and merges with the real world, and is entered through the mirror, is called the Mirror Realm. The person who created it is the savior of this world - a person with mirror ability! This is a game that can save the world, and those who participate in it are called beast hunters!
