That moment when you've read them all
aww then just follow the tag "isekai" maybe you will find new ones
Read "omniscient reader's viewpoint" it is still new. It's not isekai per se coz he did'nt get transported, more like the world turn into something... But the novel is already finished and it is so epic.
Can anykne recommend an Isekai manga that doesn't involve a harem and with lots of world building?
