This should be called Timeskip Ghostwriter. xD
Seriously though we had like 3-4 timeskips already, seems like they really want to rush into the Teppei-Aino rivalry in WSJ. They must have cut a tons of chapters in-between. Feels like they got absolute terrible feedback for ch.1 and the chapters afterwards and are now rushing it as quickly as possible, either in hopes of gaining fans, which like Halloween has pointed out will not win that many favors with them due said cuts meaning missing a lot of stuff, or to get a satisfying ending, sort of.
I think Teppei really needed a human companion for this, someone he could talk to, share this crazy story with and help him create better WK chapters. And then besides the whole Timemachine stuff, it should have done it a bit more "Mangaka" like as like that vertical line stuff he told Aino - we saw nothing of that, just speech bubbles explaining it but like seeing a blank panel and then have Teppei do the technical stuff to create depth and such would have been nice just like how nice it was to see the technicalities in Bakuman. Like Aino was perfect for this role as Teppei's helper and student - she could have helped him gain insight into how she as a ten year younger version might have done it, thus giving him the brainstorms he need to get the crazy ideas he need to make WK WK. And on the other hand Aino could have been shown, and thus us readers as well, how to properly draw manga, create panel flow, plan ahead, keep work environment good with the assistants and so on. And that just isn't happening. All we get is Timemachine spitting out infos and Teppei martyring himself while Aino is side-lined as an assistant and "rival" with all the WK chapters and development of manga and how to properly draw and assistants and Editor - all of that is unused! Remember Hattori as Editor? Like it wasn't boring listening to his critics and why he thinks readers would find this or that confusing or how their new Editor pushed them to do gags and comedy? Like what did this guy do except say "doesn't quite feel like WK", no shit Sherlock, how about you say what exactly is missing that could make this more unconventional as WK is perceived by you, the other Editors and the whole WSK readership in general?
Honestly if those timeskips keep up then this might get an axe even before Bone Collection and that one went seriously rather quickly lately.
