Asmodeus is the older twin of the two royals, and rules the Kingdom of Yellow. He is strict, ruling with an iron fist. He collects high taxes if his expenses run low, and has whatever he wishes with no opposition. His younger twin Satan serves as his right-hand man despite them being seperated at a young age. He has fallen for the Prince of the Blue Kingdom Solomon, and is envious of the Green Princess, who the Prince is engaged to marry. He plots to burn the Green Kingdom and slay the Princess.
