luciel is slightly cold, and thinks very rationally, however he is super sweet.

He is angel, but for some reason made unaware of it, and will be for a long time. Pretty much not even thinking of this possibility that he might be an angel incarnation on earth. 
And even if the thought comes up he will definitely deny it to himself, only cause he doesn’t want to feel entitled.

Luciel is very understanding, and giving. 
In his world he has some abilities related to the fictional world’s System.
