Hi, so I'm trying to find this webcomic/manhwa/manga, I don't remember. what I do remember is that the story takes place in a semi-historical society where magicians are the norm. It follows a young blonde fellow whose secret identity of that of the famed black???? magician?????, i think is the name. He then gets shipped off by his boss/guardian to a magic school and then gets involved with demons(?). That's the general plot as I can remember and up to where I read.
