Best-Selling Sci-Fi Series Had The Best Use Of Isekai Before It Became Popular

Undoubtedly, isekai stories have experienced a surge in popularity over the past decade that has mesmerized anime fans worldwide. One reason why isekai has grabbed public attention is due to the genre's versatility in its storytelling methods. That versatility allows contemporary isekai creators to write stories that seamlessly mix fantasy, adventure, and romance. Unfortunately, despite the genre allowing for such diverse worldbuilding, many have complained that a majority of modern isekai struggles to stand out amid the endless sea of "transported to another world" content. One series, which debuted well before the genre was properly established, shows just how dominating an isekai story can be when creators make full use of the genre's flexibility.
