After Becoming a Cutie, I Slay Gods, Burn Immortals, and Suppress the Ages

(Transformation) (Single) (Eternal Life) (Invincible) After turning into a girl, she lost her memories and can only remember that she used to be a man. What is she supposed to do?

When she looks back, only she remains, along with the entire world.
