No name exists. For convenience, people call her "Rei." She is sometimes observed in the form of a girl. However, that form is not the true body. The concept of a "true body" does not exist either. She possesses no emotions. She possesses no desires. She possesses no purpose. She possesses no values. She possesses no sense of good or evil. She has neither enemies nor allies. She has neither victory nor defeat. "Rei" chooses nothing. However, the state of choosing nothing is not a choice either. She simply exists. That existence cannot be attacked. She does not defend. She does not nullify. She does not counterattack. She does not resist. She does not win. She does not lose. The world cannot cause anything to happen to Rei. Rei does not cause anything to happen to the world. From the world's perspective, only the result that "nothing happened" remains. Some who observed Rei say she was a girl, while others say she was light. Not a single testimony matches. The only consistent record is: "She was there." That is all.
