Without really knowing much about Bakuman, which is of course the more popular series, I think it has some similarities setting-wise with Time Paradox Ghost Writer that it tells a story about how the manga industry works and how to become a mangaka in the first place. So in that it sets itself up from most of the other Shounen publications that it features no superpowers or actionopacked fights which is a nice variation from fighting mangas that could feel repetitive in the long run. Its interesting to see how metaphysical the series is in talking what makes a manga worth reading while being a good manga itself so the author maybe could self reflect in this moments and learn even more about himself how to make his series even better. The science-fiction element is quite unusual with the time travel depicted but creates mystery about the origin of this incident and could give some room for funny predictions of Shonen Jumps future that could partially come true.
The art is not much to write home about but sufficient enough and compensated by the orginal idea.
The both main characters are linked in an uncommon way to drive the story forward but thats what I like, so the development seems unpredictive. Sasaki, the guy, is written relatable with his past and especially inner recent conflicting struggles. The girl is rounding up the main protagonist to say the least. And the editors deciding which manga is going to be realeased are portraied in different facades, what I found good, so not all are the same grumpy logical thinkers.
Overall it is a good manga series about manga and is approved by me for publication(if I were a Jump editor of course) but that already happened before. So read it if you like to learn more about the manga business.
