Recent chapters have been full of boring battles, as I'm sure many of you have noticed, and I was wondering why, after so many great chapters, Hoshino would draw these annoying long fights instead of developing the plot. And so I thought about it and came to a conclusion: maybe she wants more guys (that is, the ones who would normally be reading JUMP) to read DGM? Its ranking on the table of contents in JUMP isn't usually high (and that indicates popularity), but DGM volumes apparently sell quite well. There are clearly lots of yaoi fangirls of the series. So maybe Hoshino would rather have a male audience rather than them?
There are two things that made me think about that:
1) The fights. Little boys like fights, as shown by the Top 3, and maybe she thinks that drawing fights will attract them to this manga (hopefully, once its popularity increases(?), we can get back to plot). That's something that yaoi fangirls would probably enjoy less, too.
2) Lack of Kanda. He's never played a really big role in the manga, but it feels like Hoshino is trying to write him out of the story a little... which doesn't make a lot of sense, considering that he's the most popular character. Of course, he's loved by girls. Since volume 3, he's only appeared a few times, and his fights have been short. His Innocence is now broken and he can't fight. It's also been rumoured (see Mangahelpers) that Hoshino is planning to reveal his past this year. If she does that, it'd be way easier to get him out of the story.
And then we have Sokaro, DGM's equivalent of Zaraki (except with a far greater possibility of death, in my opinion).
So am I just reading too much into this? She did include those assistant's drawings of half-nude female characters, or Shueisha did, anyway... Well, as long as the plot takes priority at some point, I'd be happy about such a decision...
