I think the initial setting is quite good. The execution is really bad. It's like the author tried writing 2 different stories, wound up with not enough material for both, and decided to put them together somehow to fill up a book.
the intro was really good, but why go back in time and tell us the main characters story? and the sister.... and now some random woman from who knows where who can somehow fly... where is this going??!!
it looks to me like the author is trying to add multiple stories into one, which don't coincide with each other as they are a little all over the place... fix the story author-san...
At the beginning of chapter 10 is about the other classmate that was summoned to the isekai(which I don't give a fuck). The important part there is actually the difference of Hero status/skill and the MC status/skill. The flying girl 'Lina White' is an angel. I don't want to spoil any further than this but the story will add up.
@Yarramie WN stand for "Web Novel". Basically it's like the beta version of a Light Novel...
Many authors in Japan (and elsewhere) get their start by publishing a story they wrote online, for free. Later on, if it gets a large enough following, they can edit/change that version to release it proper as a Light Novel. Kind of like Overlord and many other series started as Web Novel but made the switch to Light Novel later on.
You can view see a translated version of the web novel, by clicking the "NovelUpdates" link.
I don't think it will... first two chapters were consistant where characters were in a new world and learned how to use their new overpowered powers, then it suddenly turned to a sis/bro complex up until chapter 8, it suddenly turned into a fight between the main female protag who had gone missing in chapter 9, which came out of the blue, and now there is an introduction to a new character who came out of nowhere who is out of blood, and somehow time-travels to japan.
I think it is safe to say that the author has no idea what they plan to do as they changed their mind last minute, or, this is collaboration of multiple writers with different ideas but keep the same artists which makes more sense (to me at least). Hopefully this becomes better before it turns totally upside down, but I wont keep my hopes up.
For me it works fine though, you probably over thinking about this. Of course the story is gonna move on the relationship between the MC and heroine around him. A new characters being introduced is expected in any story.. The hero party is related to the story that is why they are mention from time to time. I've been reading the web novel and it all make sense to me..
Maybe the web novel makes sense, but the manga is jumping from one situation to another without much flow. This is why many people are freaking out about this manga. It would work well if there was some introduction at the end of one chapter to another but that is not the case.
