Black Diary: Liriell's New Chapter

Liriell, a mysterious girl who lives in the human world as a flower arranger at the Flower Gallery store, holds a profound secret about her origins. Beneath her warm and cheerful demeanor, she is actually a white elf banished from her people and has lived for hundreds of years. Her serenity begins to crumble when Velmor, a cunning, half-mad dark elf who has long haunted her, reappears in search of the Black Diary—an ancient magical artifact that holds the link between Liriell's soul and her people's past. A misunderstanding manipulated by Velmor leads the wizard Isran to hunt Liriell, leading David, Mr. Magic, and Fernando to become embroiled in a magical conflict that slowly escalates into a battle between light and darkness.
