The most interesting characters in 'The Rising of the Shield Hero' English novel are numerous. The Shield Hero stands out with his tenacity and ability to adapt. Raphtalia, who starts as a slave and grows into a strong warrior, is also fascinating. Filo, with her endearing yet powerful nature, is a great addition. And the various villains, like those who plot against the Shield Hero, are interesting in their own right as they create the conflicts and challenges that drive the story forward.
The Shield Hero himself is very interesting. His journey from being an outcast to a powerful force is captivating. Also, Raphtalia is an interesting character. Her growth and loyalty to the Shield Hero add depth to the story.
In my opinion, Filo is quite an interesting character. She has a unique personality that combines naivete and strength. Another interesting character is Malty. Her devious nature and the role she plays in the Shield Hero's misfortunes make her a character that you love to hate. There are also many other side characters that add different flavors to the story.
