Lise

Ian's aunt, she bears a striking resemblance to her sister Kureha, enough that her father could confuse them. Her real name is Lucifera, and like Kureha she is of the Leannan-sidhe. Unlike Kureha, she was a customer of Kaito's shop, and now no one—not even Ian—could tell she is a fairy. Further unlike her sister is her rather wild attitude, she has no problems with breaking into houses and disabling security systems. She quickly senses Ainsel's power, and asks Kaito whether he is planning to destroy the world. It is implied that she has feelings for Hasumi, though nothing comes out of it. (Source: Wikipedia)
