No, I mean I think it will be successful becouse is different of all we have now, basically sports and romcom series, not because is dark. Also, I don't think is as dark as has been said.
And if a dark manga isn't good, the jump readers won't vote for it, even if they like the style (I think it's not the word I want), and the same for adventure, sports, romcom, or fight series. If a manga isn't good, it will be axed. And I think the two chapters we had are good enough to be, at least, a year and a half in the magazine.
