I'd add some description to the links. – Sunni Rashad2 months ago
The first link is to a Wikipedia page to help define what isekai is, in case the topic taker is not familiar with the term. The second link goes into popular types of sub-genres for isekai. The third link is to a Reddit post that asks why you could perhaps neglect to mention that the main character is from another world and it wouldn't change anything about the story that's important to the plot. The fourth link discusses why isekai is so popular in anime. – Siothrún2 months ago
