Chalcedony is the commander of the 13th platoon of the Crystal Knights, and is Paraiba Tourmaline's fiance. His underlings, Peridot and Pyrox, set out on a quest with him when the Crystal Knights see Kohaku's Spiria shards shoot through the sky. The goal of their quest is to recover one of the "mysterious objects" for the church to analyze.
Since being trained as a Crystal Knight, he has become very stiff and formal. He is irritable and easily embarrassed at first, but gradually grows closer to the party. After the deaths of Peridot and Pyrox, Chalcedony begins to heavily rely on the rest of the party for support in both every day life and his interactions with Princess Tournmaline, whom he is still very awkward around.
