The most vulnerable being in the world. If you speak to her, she will die from brain concussion caused by vibration of air your voice makes. For the same reason, she cannot speak. Also, if you move, the motion makes wind pressure and it kills her. When wind pressure exists, she must die. However, you have a button to reincarnate her, but she is still the most vulnerable even after her reincarnation. If you don't want her death, do nothing. The rule of her vulnerability cannot be changed.
