Lucy's past links with Kohta are uncovered - after her dog was killed, she began to show contempt for humans, until Kohta briefly befriended her. Kohta plays the series' opening theme "Lilium" in a music box which he bought in Kamakura. They go to the zoo and later play in the water, where she thanks Kohta for the most fun she'd ever had in her life. Her hope in being re-acquainted with humans is briefly regained. However, when she discovers Kohta's cousin (Yuka), who he claimed to be a boy, is actually a girl, she loses hope and begins her future murderous path. (Source: Wikipedia)
