Description

Krul is the third progenitor among the vampires and the vampire queen in Japan. She saved Mikaela's life against his will by turning him into a vampire, but this appears to have been done for her own personal interests. She is also the only vampire who shows him kindness, and there are several moments when she hugs him or treats him gently.

Just like all other vampires (minus Mikaela), she views the humans as nothing more than livestock. She sees them as foul and endlessly greedy creatures who will do anything for their own personal gain. Krul keeps many secrets, including what she knows of the "seraph of the end," and she is deceitful toward the Progenitor Council about her criminal activities. Like most vampires, she is proud. As a third progenitor and the queen of Japan, she has reason to be and the power to back it up. When Third Progenitor Lest Karr challenges her position as the ruler of Japan, she becomes angry and claims she never fails, ever. She is temperamental when challenged and does not hesitate to remind her challenger of his/her place.
