What would an Isekai manga need to do in order for it to work in Jump? I had originally was going to give my support for a Jump Isekai manga as I thought it would be interesting but... honestly, I’m really conflicted now.
Personally, I do think that an Isekai manga would have to adopt battle shonen tropes for it to have a chance in Jump, which I think should means that overpowered MCs in the beginning of the story wouldn’t work. It would be relatively easy to get kids to relate to the MC, since Isekai MCs are usually self-inserts anyways. But I also think that most Jump MCs have to be inspiring in some way or fashion. They always strive to become better, stronger people. I guess I’m saying that the MC would have to be an active one, instead of the usually passive roles we get.
As for the love interests, well, some Jump MCs feature quite a few girls taking a liking to him anyways, so an Isekai would feel right at home here. XD
Like most genres, I think it’s honestly all about execution. If it’s a good manga, Isekai or not, people will read it.
