Vage is a demon, in a way. he exsits in two worlds: shadowsLite and normalLite. he contorls the bodies of people since in normalLite he is just a evil spirt.
he is able to give his insanity mark to 1 person in normalLite in his shadowsLite life time. sadly that person is Kira. she turns slightly more insane and more accepting of it each day.
I love backstories!!! :3 srry i spelled insanity wrong in the picture. :P yeah.... CHARACTER DEVELOPEMENT :D
