@Grimmycoffee I understand the appeal of warfare theme (awesomely shown in Kingdom) but the funny thing is that Kingdom was never focused solely on that. First battle depicted (Dakan Plains) was after 30 or 40 chapters. The two main themes are "unification of china" and 'path of a commoner becoming a great general". And the manga arcs were always interlayered with political and moral themes. Well, morals not so much. And I see this new girl being an opportunity for the manga to approach it with more depth.
But I'm not disagreeing with you. I get the supernatural stuff diminishing the realistic and historical aspects. But Kyoukai, since beggining has been it (a supernatural force, as revealed several years ago). Let's just view it like a way of mangaka to depict the chinese legends as well, which is also part of history and culture of Ancient China. I mean, it's not that I don't get the complains, it's more that I think people should not focus so much on the pure battle strategies aspects, they are not the only things that matters in military conquests...
