Librarian

The Librarian is a recurring character from the 2018 Netflix animated series Hilda. She was created for the cartoon and its tie-in novel adaptations, and does not appear in the original Luke Pearson graphic novel. As her name indicates, she is a librarian with an uncanny ability to find the exact book that Hilda and company are looking for. She has black and purple hair and usually displays a calm personality, although she can be quite stern at times. In season 2 episode 3 aptly titled The Witch, her name is revealed as Kaisa, and is also revealed to be a witch. The character is voiced by Swedish actress Kaisa Hammarlund.
