Boo Cat's lover, a vampire who dresses as a goth cheerleader. Her real name is never mentioned, but she takes the name Licorice because she is "sweet, and very bad for you". Licorice is quite committed to Boo, and has no other known lovers.

Licorice started the series as a somewhat shallow character, resenting humans for their fear toward her. She has quite a bit of rage, which she has channeled into being vigilant against those who hurt women and children. Due to her vampire nature, Licorice is supernaturally strong and agile, making her a blunt instrument when enraged.

Recently, her rage has spilled over into jealousy and resentment toward Tarot, as Boo's other lover. Licorice's actions have caused a very serious schism between herself and Tarot.

Part of her past was revealed. She and her friends were goths that willingly became vampires by a male vampire and killed him by wooden stake rather than be his sex slaves. She sometimes has reunions with her Goth-cheerleader vampire friends.
