Actually this seems to be a dojinshi(work self-published by author) so probably there's no editor? The last page is the usual dojinshi style end-cover warning us not to put the work on auction (which you don't see on regular published works).
Echo Jiro: FUCK I'M FRESH OUT OF IDEAS
Editor: Um, you kind of need to put something out soon so maybe try brainstorming?
Echo: NOPE, IVE GOT NOTHING, HELP

Editor: What.
Echo: SANTA GETTING FUCKED. BOOM, CASH MONEY.
