Reighan
Garanzo's right hand demon. Reighan is responsible for Char's unfortunate situation. He was the one who discovered Char and 'introduced' him to the Fire Lord, Garanzo, and as such, Char detests him with all his passion. Reighan on the other hand, adores Char's presence with his master, as when Char is around, Garanzo is extremely more tolerable and less likely to destroy his servants.
Since Reighan is the king's silver tongue, he translates what his master may be too 'busy' to say to his subjects, and he knows just what words to spin to avoid getting himself slaughtered by his king.
Garanzo finds his voice and words to be somewhat soothing, and can aid in calming him down when the fire lord is in a dangerous mood. As Garanzo's 'go to guy' for anything and everything, he is also chief of the castle's staff. All Reighan's words are chosen carefully and with purpose, for any mistake may be his, or another's last.
