From the moment I was born, my parents hated me just because I was a girl. Under my grandfather's rickety body, I lived tenaciously. When I was 18 years old, I left this world in a broken state, either because of a trick of fate or because I was unwilling to do so. With my special powers, I returned to the world to challenge fate and reorganize the world order.
The idea: Children who grow up in a miserable world can achieve self-salvation after possessing superpowers, and then change the world.
