With 6 new series, I think it is interesting to make a ranking of chances of surviving and make some comments. Now that we have two, let's see...
1) U19
Right at the the color page I saw that it has an art rough around the edges, some strange proportions, I think, but it can improve during the series and I think that U19 has the potential to survive. The premise is interesting, it kind of reminds me of Assassination Classroom in a sense that it has a ranking and segregation around scores although it seems a little lighter, people are not mistreated like AC. I think it is also a critic to the Japanese society as well, though a bit exaggerated to make it comical, and can resonate with the readers. There is also the entire science fiction aspect of the series with this hidden power thing. I think the story showed that there are many things to develop, things to make us curious. I think the next developments are predictable, the protagonist will awaken his hidden power and fight with other kids in the organization to change things and save his beloved one. However, after this, many things can have and it is exciting. Let's see, I liked the first chapter.
2) We never learn
Although it was advertised as romance, there was no romance at all in the first chapter, U19 had more romance than it. It will probably develop afterward, but how the romance will come together with all the study thing... If the protagonists chooses one, things will get awkward and ruin everything, only the mention of romance can be distractful and ruin everything since we know how Japanese people are self conscious about such things. The premise doesn't have much to develop at first glance. The all studying thing is boring, studying IS boring, principally for high school students and below. How well the author will handle this to make it less boring? Things will have to happen, only see them studying in a table will make the readers get bored very quickly. The characters are likable though, if the series focus on them, it can become more interesting. I still have to read the second chapter, let's see if it gets any better.
