Eruruu is a seven-petaled flower that blooms in warm weather with white pink-tipped petals. They bloom alongside Aruruu Flowers and because of this it is said the flowers are sisters. The flower gets its name from The Story of Eruruu and Aruruu, and is also the name sake of Eruruu. Presumably, it is also where Tuskur's older sister Eruruu got her name from.
