A transfer student with no past walks into the most dangerous school on the planet and immediately becomes the person everyone is watching, because something about him breaks the rules they all live by. The show doesn't waste time explaining what makes him different. Instead it puts you inside the paranoia of kids who have everything to lose, trying to figure out if this one kid is salvation or a weapon pointed directly at them. By the time you understand what Agate actually is, the entire power structure of the world has shifted, and you realize the school was never teaching them how to lead, it was teaching them how to survive knowing too much.

Agate Fluorite arrives at Cluster Edge Academy as a transfer student. The prestigious school is where the sons of the elite prepare to run a world in which artificial soldiers and religious sects fight for total control. His cheerful, unpredictable behavior and innocent smile stand out against a gloomy student body tired of routine, and even aloof honors student Beryl Jasper takes notice. From the start, Agate sits at the center of mysteries he himself cannot explain. He also carries a secret about his birth and a power to work miracles. Whatever he is may be momentous enough that the world behind the academy cannot survive it. The show mixes action, fantasy and science fiction.
