I hadn’t heard of this one, but the visual had me thinking it was a manhwa. I just looked up the synopsis and it makes the series sound quite ominous: “At first, Kirishima seems amiable and polite–but when he shows his dark side, he proves to be more disturbing than any gangster Yoshino has ever met.” Also looks like the series has won several awards before as well. I haven’t taken a good look at the Fall season yet, but this sounds interesting.
