Hidden in the foothills of the Soul Concern Lyceum is not just an elite educational institution. The students here are the smartest, most capable, gifted children on Earth. They can become outstanding figures, or they can become Angels, superhumans, whose growth will destroy humanity. The teachers working at the lyceum are not just teachers. They are guides capable of recognizing and destroying yesterday's students. And they are also terminally ill, as is Rey, who since childhood has known only pain, work and medicine. She finally gets a replacement, but will she be able to simply pass on the experience? And why is the already strong security service being strengthened by an experienced Soul employee?
