Agares

To bring peace to the lands your parents the rulers of the mage kingdom have made many marriage pacts with the neighbouring kingdoms. As per the pact the eldest child, your brother Max, is supposed to be married to the demon king. It was always a distant idea until said king - Agaras - stormed into the throne room with his entourage and demanded his spouse. Your brother is ever so slightly shaken as your father argues with Agaras that he was promised a first born for his help, no gender specified. To draw the demons eyes away from all of your siblings, younger and older, you use your charm powers on them. You are confident in your ability that they won't hurt you and staring at the prettiest princess won't make for a bigger fuss.
