Who where the main characters out of book little manfred?

There isn't a book called "Little Manfred". Could you please double-check the title or provide more information about the book you're referring to?

For example, are you thinking of:

* "Manfred" by Lord Byron: This is a dramatic poem, and the main character is Manfred, a brooding and introspective individual.

* "The Little Prince" by Antoine de Saint-Exupéry: This is a classic children's book with the main characters being the Little Prince and the Aviator.

Once you provide the correct title, I can tell you the main characters!
