Chalce was a Cluster E.A. student who was killed by the military for fighting and associating with the artificial soldiers. 

~!Chalce's theory about Artificial Soldiers is that they are able to manifest human emotions after receiving education and also part of the memories from another person. His memories were implanted in Agate and Chrome.

Later on his diary was found, revealing more about his past. "Agate" was originally the name of his private artificial soldier but since Chalce taught him to speak and many other things, he became much more - his first friend. When his father did not approve of their friendship and tried to destroy Agate, Chalce interrupted and accidentally killed his father. Chalce met the new "Agate" on a few occasions, last one being the moment when his plane was shot down.!~

Cluster Edge Academy isn't just any school; it's THE school, where the offspring of the elite come together to prepare for their roles running a world where artificial soldiers and religious sects are major factors in the battle for total control. Which may be part of why new transfer student Agate Fluorite doesn't quite seem to fit in. It's not just that Agate's enthusiastic attitude stands out among the somber, brooding balance of the student body. There's something about him that demands notice, even from jaded honors students like Beryl Jasper, and from the moment of arrival he's been at the center of a series of mysteries that not even Agate understands. Because Agate's not just another student, he's part of a something so momentous, and dangerous, that the world that built Cluster Edge may not survive its passing.
