In Japanese, Fuse's isekai web novel about an office worker reborn as a slime in a sword-and-sorcery world sits at the advanced level of our library. It needs a very large vocabulary, which reaches the highest JLPT level with many words on no JLPT list, and kanji fill much of the page, with fantasy words such as monsters, barriers, magic power and labyrinths. A large cast and coined names for races and skills, spread over a very long serial, add to the load, yet the genre words come back again and again, so learning them early pays off for the rest of the book.

MnemoRead measured this book from its full text: how many of the language's most common words you need to follow it, and how long its sentences are.
