Parts of Kuon's personality are only revealed by various characters in their arcade scenarios. It is mentioned how, in the past, he was a man of virtue and honor, having inspired Waldstein with his chivalry and being well-respected by many.

However, due to unknown circumstances, Kuon's personality appears to have taken a mysterious and possibly sinister turn, seemingly having severed ties to his former allies and manipulating Hilda into becoming his willing pawn and seemingly discarding her when she was of no further use. In the present day, Kuon comes off as cold and uncaring, mainly keeping to himself around others and preferring to keep his emotions out of conversation, giving him an eerie, sinister presence.

While Kuon is a natural combatant, he prefers to stay away from combat whenever possible and will not fight anyone unless he has a reason to, and even then, he will only resort to fighting as a last resort.

His voice should sound like a young teen, with an air of mystery behind it. While almost cynical, he could come off as someone who likes to play jokes on others. That should most be portrayed in the second line.
