Chalcedony Renierite カルセドニー・レニエル

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

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.!~
