This is a depiction of Lyon encountering the Demon King for perhaps the first time. The black tendrils of shadow are coiling around him, probably whispering strange and arcane things. Lyon’s kind of scared, but he’s doing experiments in the name of peace – it’s to cure his sick father. Unfortunately… well, bad things happen. Poor Lyon.
I actually like this picture better than the previous one, but I don’t like that way of doing hair very much.
