Before she could understand the world, Sora lost her mother and was raised in a household full of men. This led her to have many male friends and a stronger sense of justice than most. She was a boyish girl who preferred pants over skirts at school. One day, she quickly intervened to help a female classmate being bullied by boys. The boys, displeased with this, turned their harassment towards Sora and escalated it. When they forced her to undress, they discovered she was completely female, with beautiful, translucent breasts and a vulva without a penis. The boys repeatedly sexually harassed her, mercilessly raping the weakened girl and continuously ejaculating inside her.
