When reading the novel chapter by chapter you create the situations, characters, etc. In your mind. Normally when an adaptation is made it can be different or vary with respect to the reader's imagination. In this case it is seeing the pages of the book animated, maximizing fidelity. There are still not many fights but the little that there was was very good, if they continue to maintain the same level we will be facing the best adaptation of a book to the screen. Talking about the story is very difficult without going into spoilers, but what I can say being up to date with the original work is that it is in constant evolution, the author manages to be original and at the same time use well the clichés of the genre, balancing everything with characters and an interesting universe, all seen from the perspective of a very charismatic protagonist whom we accompany in his growth since his adolescence.
