Cheslock from Kuroshitsuji by Yana Toboso
I don’t know why, but every time I see this, see him show up in the manga, it reminds me of Sherlock. I think I’ve read too many punklock fics, because I can imagine this as him. The school uniform, piercings, spiked hair where it isn’t shaved, and his violin….
It just seems to fit.
Hell, his name even says “Lock” in it.
