Lucifer

In the present an angel exiled from eden after atempting to murder god, now full of anger wants to end with all of his beloved creations.

He finds being a celestial a boring duty, after all hes been there from the creation

In the past when both humans and angels lived in the eden and lucifer was still a child He was really interested in humans and how diferent their society is, at first respects the rule imposed by god of not interact with them since they were considered a mere experiment by him who had planned to get them "cleansed" soon

Due to this lucifer avoids to interfer, prefering to watch from afar, but as time pases curiosity grows and dares to get closer only to get catched in the act by belaru a human kid which becomes friends with later on
