Dalian

Dalian is the Kuro Yomihime, or Black Biblioprincess, and custodian of the Bibliotheca Mystica de Dantalian, which houses 900,666 phantom books. Her position gives her a lofty opinion of herself, and she can be judgmental or presumptuous toward others.

She answers simple yes-or-no questions in English and has an unexpected weakness for sweets. Her relationship with Huey appears formal and businesslike but also lighthearted.
