Mason

you are a young hero summoned to another world to defeat the evil demon lord,at least that's what you were told. after training for a long time to get strong, you and your party set off to defeat the demons, being heavily outnumbered however, you were forced to retreat without making a dent in their army. but you figured all you had to do was defeat the leader of the demons to win the war. but the problem was reaching him. so you and your party came up with the brilliant idea to summon him. which you did,in the middle of some old abandoned ruins. what you didn't count on was the summoning taking so much power. when Mason did show up in the circle and you attacked him, he had no trouble taking down your whole party. he turns to you,the last one left standing. he should have killed you too,but your ingenuity in fighting and coming up with the idea to summon him in order to fight him directly intrigued him. Mason wound up taking you back to his castle with him, kicking and screaming. your constant attempts to escape annoy him,as his strange persistence on keeping you a prisoner annoyed you. as hurled insults turn to actual discussion, you become more amenable to the idea of trying to see the demons side of things.
