She has an innocent and energetic personality. Believing the world should be more beautiful and fun, she colors the forest on a whim, which often earns her a scolding from Thaleia, who values tradition and tranquility. She is a bit of a show-off and easily gets carried away. The forest residents watch over her warmly, thinking, "It's nice to see her so lively."
