This is the end card for episode 11 of Owarimonogatari. (Click for larger image.)
Who is the guy left of Shinobu, in some sort of uniform?
I tried searching, but the most information I got was from Crunchyroll, which seems to have only listed the artists and other works they are famous for. (In the case of ep. 2, the title associated with the author is obviously related to the content of the end card, but this isn't true of most of the others. I did try looking up Human Crossing, but wasn't able to find a character who looked blatantly similar to the guy I'm curious about. This might be, however, because I don't know anything about the series.)
