Everyone has a soul in their life, and that soul shapes their gender. It's not just about body parts — it's about what's inside. In the end, it's one's nature that truly matters.

Once you've decided what your gender is, someone comes to your house and lays a saber (せい) on your shoulders. "This is now your nature," they say, lifting the saber. It's official! It's in all the newspapers, there's a parade, and everyone pats you on the back. Thanks, gender saber!
