It's not bad, in fact, it's incredible how well the two worlds were fused. Of course, despite being a great story, at least as far as I read it, it has characteristics that I personally don't like, it's up to you to decide whether these characteristics are benefits or deficiencies.
1. It's an amalgamation that diverged, basically instead of an expected fusion where the author just changes small parts to merge the two worlds without too many problems, you have a version of the world where it really seems that due to the overlap, there are several divergences with the two stories, whether in world building or character characteristics. Of course, I really admire the author for creating such an elaborate version of the merging of worlds without making me feel like it's stupid or impossible, but a truly possible version, yet, due to me liking how the two worlds worked before, i do not like how this overlap turned out.
2. 2 is actually a continuation of 1, due to the overlap where there is a huge difference between the plots of the two stories, the world created a wide range of mysteries, due to how the author approaches the story, many of them must be unraveled little by little with the fluidity of the story. Basically, I don't like mysteries, especially in Fanfics, even in original books, this type of story full of unknowns often irritates me, which is why I hate detective stories and things like that.
Of course, this is all personal opinion, that's why I still gave it 4 stars, even with my personal dislike, I really recommend this story if you, who don't have my two problems above, are interested in reading it.
