@Cruithne:
Not sure what about Roggy made Jump willing to keep their offer open until the author graduated college. Hopefully it'll get better.
For his age, the one-shot was extremely high quality, and he's done two other one-shots in the meantime, both of which were pretty well received. One was another Roggy story, the other was about a samurai/exorcist in medieval Japan. For a rookie to have such clean, refined art and solid page layouts is impressive. Even the original one-shot looked like something by a veteran artist, and he was only 16 when he drew it.
Cyborg Roggy has great art and character designs, but the first chapter wasn't especially exciting. A more elaborate battle sequence, amazing special powers, or a cool transformation would have helped a lot – but this series has a lot of potential for that in the future. I like the characters and setting enough that I want to see more of it, at least. And even if it's not a hit, I think we'll see big things from the author in the future.
Black Clover is frankly like a paint-by-numbers of how to make a successful shonen manga, which means that it'll probably appeal to a lot of people, but for me it just feels formulaic. I expect more discerning readers will find it unoriginal – it is basically Naruto, with hints of other mainstream series thrown in. I feel like I can predict how the next chapter will play out, and how the first arc in general will go.
Kagamigami has great art and a really interesting world, but it's not doing enough with it to get me really invested. The third chapter's a big step in the right direction, at least. There's so much cool stuff that can be done with the shikigami concept, and I want to see more of that.
I'm still not really interested in Ultra Battle Satellite because I'm not a big fan of sports manga, but I'm curious to see what it has to offer.
