Diamant has a serious personality with much fortitude and vigor. As the crown prince of Brodia, he takes great pride in his nation and hopes to be a great leader much like his father. He greatly respects his father and understands his mindset and intentions, much to his sometimes frustration for his father's recklessness and sense of honor. He is close to his younger brother Alcryst as well, gently encouraging him and is patient with his self-defeating attitude.

I'm open to interpretation for this role but if you wish to know what his character actually sounds like:
