Byouinzaka Kuroneko from the Sekai Series by Nisio Isin. An all-time favorite character by one of my all-time favorite writers. She is a glorious beast to behold, and the kind of character I've never seen in anything before or since. As opposed to many of my older illustrations, I actually still quite like this one. I feel like I was able to communicate her energy srelatively appropriately, though of course it's impossible to get the full scope without actually reading her insane dialogue.
