Small characters descriptions and Image(I drew them my self)

I don't really know who the idea came to me. I watch to much demons anime(rewatch Blue Exorcist and is now reading it) /movie, maybe it's because I just discover Demitale(A/N I DON'T KNOW TO HOW IT BELONG TO) . I don't know my self.
But basically in this Au all of the undertale monster are demons hunters (exorcists).
Humanity have been overtaken buy demons.
Frisk climb mont Ebott in hope to escape what her world had become.
Chara was the first human to fall but when they died since they refuse their fate they became a demonic spirit. They hate both humans and demons even if they are/were one.
