15th Man Submissions Thread: Character Concept

The Knight and the Beast
He would have a double personnality, each taking control of the body exclusively.

The Knight
Before the curse, he is shown as kind and honorable. After, the player can see his internal struggle, his will to fight the empire and his fear that it might wake up the demon within him. As a comedic relief to the rather deep story of the other personnality, he would often see himself embarrassed when the personnality change occur and puts him in weird situation.

The Beast
An esper trapped in a mortal body,his will for revenge being as big as his power.
He first seen as a curse, a mere unexplicable power. He first try to hide but as his will for revenge become bigger and bigger, it is made obvious that he is a double personnality, seen as a cruel monster with unknown intention. As the beast live and learn from the party, he begin to open itself and slowly reveal his dark story in the war magi and how he was trapped for 1000 years. The party then become sympatic to the beast cause.

I know this is more "history" than "what kind of person is this" but it wouldnt have any sense to explain his personnality without history.
