The Spy x Family novel has its own charm. While the anime is great at visual storytelling, the novel can be more detailed in terms of the inner monologues of the characters. It gives you a different perspective on the story. For instance, Anya's telepathic experiences are described in a more in - depth way in the novel, which adds another layer to her character.
It depends on personal preference. Some people might think the manga is better for its original storytelling and art style. Others might prefer the anime for its animation and voice acting.
The connection between the anime and specific manga chapters isn't straightforward. It often depends on the creative decisions of the production team to adapt the story effectively.
I'd suggest starting from the beginning of the manga. Sometimes the anime leaves out little details or nuances that you can catch in the original source. Plus, it'll give you a deeper understanding of the story and characters.
Well, Spy x Family fanfiction can be really interesting. Some fanfictions might explore different relationships between the characters in more depth. For example, they could focus on the bond between Anya and Loid in a new situation that wasn't shown in the original manga or anime. It's also fun to see how authors play with the spy and assassin themes in unique ways.
