Sang'gre Mira of Lireo, Diwani of Hathoria, is the firstborn daughter of Sang'gre Pirena with Gamil's child a diwata soldier. Switched in infancy with her cousin Lira by her mother, Mira grew up believing she was the true heir to the Diwata throne.

Due to Sang'gre Pirena's ascension as Hara of the new Hathoria, Mira becomes automatically the heiress presumptive, being the former's daughter. Mira was promoted as a full-fledged Sang'gre of Lireo after being trained by Cassiopea.

She is Lira's best friend and closest confidante. Due to their closeness, they consider themselves as partners-in-crime and sisters. She was chosen by the Water Gem to become its new master succeeding Sang'gre Alena of Lireo.

She is chosen by the Water Gem because of her kind heart.

Mira becomes a half-sister to the daughter of Azulan and Pirena.
