Lira is the only daughter and sole heiress apparent to Amihan, who became Queen of Lireo and his father was King Ybrahim of Sapiro. She was hailed by her grandmother former queen Mine-a as Encantadia's luntiae or savior. She was crowned Queen of Lireo and instantaneously abdicated the throne in favor of a peaceful life in the mortal realm. She is also the mother of Cassandra.
In the first part of the story, Mira was known as Lira until the discovery of the true Lira, Mila.
Lira was born through a collective dream by her biological parents, Amihan and Ybrahim. Danaya, her aunt, blessed Lira with extraordinary powers and protection against Pirena while her aunt Alena blessed her with a beautiful voice.
Pirena knows that Lira is a hindrance to her plans. She tries to kill Lira but fails because of Danaya's blessing. Instead, she replaces Lira with her own child, Mira, and sends Lira to the human world.
The true Lira is adopted by a poor couple that names her Milagros (or "miracle" in English) because when their hut catches fire, Lira is found unharmed. Lira grows up into a pretty young woman, and comes to works as a maid for a rich family where she falls in love with Anthony, her employer's son.
After being discovered by Danaya, Lira returns to Encantadia with the help of Bagwis. Lira is reunited with her mother, Amihan, after being lost in Encantadia and imprisoned by Pirena.
Lira’s mission as Encantadia’s luntiae (savior) finally came into fruition as she has fulfilled to save Encantadia from the clutches of the Hathors when the three kingdoms of Lireo, Sapiro and Adamya triumphed in overthrowing the Hathors from its occupation of the land of the Diwatas. She successfully brought peace and tranquility in Encantadia and served her purpose in the reunification of the four elemental gemstones and their guardians.
After the war, she is crowned the new queen of Lireo but almost immediately steps down, choosing to live in the human world with her soulmate Anthony. Lira and Anthony lived a reserved and idyllic life for many years. Both of them were unfortunate not to be blessed with an offspring, but this did not deter them from their lifelong vow to be together, until the sad reality finally catches up with them: Lira's heritage as a diwata meant that her lifespan far outstripped that of a mortal such as Anthony. In the finale of the series, Anthony dies of old age while Lira is physically still at the age she and Anthony first met. Deeply bereaved, Lira returns to Encantadia and asks Cassiopea to also grant her the sleep of mortals. Cassiopea reluctantly accedes to Lira's request, much to the grief of all Encantadia, which mourns the passing of their savior. Cassiopea, however, takes strands of Lira's hair, and from these conjures a baby. Named Cassandra, she is considered Lira's daughter, being the child of her own flesh.
Lira triumphantly returned to Lireo and was met by her parents and ash’te Danaya alongside Aquil. Her return met diverse reactions and was scolded by her parents for journeying back without Emre’s consent and approval nevertheless Aquil took the benefits of Lira’s presence as she would serve a crucial and indispensable part in their fight against their opponents. Lira assured and guaranteed her full mutual aid in their quest to rid Encantadia from Etherian suppressors. Her arrival was also met with disdain as she had found out that her daughter Cassandra had voyaged towards Devas in an attempt to bring her back. Lira however felt that it would be best if her daughter wouldn’t be around all the more that Encantadia has become a perilous milieu for Cassandra, taking note of the fact that she is safeguarded by Wahid, Wantuk and Apek. Amihan on the other hand has been anxious and fretted that Lira’s return might have something to do with the realization of the prophecy concerning Ybrahim’s demise at the hands of his own child. Amihan’s sister however shoved any truth to her assumption.
Following Cassandra’s failure to disembark in Devas, she returns to Sapiro disappointed and desolated. Lira nonetheless was thrilled upon hearing that Cassandra has arrived and soonafter she reunites with her daughter she has since longed for. Learning of Lira’s return, the Goddess Ether confronted Avria because she has overlooked and undermined Lira’s return from Devas. Ether divulged to Etheria’s Queen how Lira, Encantadia’s luntiae, has liberated the realm from its conquerors and that they shouldn’t forsook the fact that Lira could jeopardize their scheme. Lira who rescued her ash’te Pirena from Ether’s clutches fought the vengeful goddess only to be overpowered by her. Fearing of Lira’s safety, Amihan and her sisters convened and decided to send Lira and their granddaughter Cassandra to the mortal realm to seek refuge away from Encantadia and to protect Lireo's future queen. Her mother stated that Lira’s mission for Encantadia has long been fulfilled and that her duties as mother to Cassandra should be her main concern. Lira arguably declared that she could carry out both duties effortlessly, but later submitted to her mother’s wishes. And so Lira and her daughter where whisked into the mortal realm.
