Lymle is a young girl that lives in the village of Triom on the planet Lemuris, she lost her parents at a young age, so the village chief, Ghimdo Triom Phi, raised her as a grandfather. She was naturally born with the ability of Symbology, and treats the Cerberus she summoned through Symbology as her friend.
Lemurians are generally small in size, a product of the environment they live in, but there is another reason why Lymle looks so much younger than her 15 years: At the age of six, an errant symbol pattern she drew opened a portal to the demon realm, sending several decades' worth of hatred and fear flowing into her heart all at once. To keep herself from breaking down, she shut off all emotional outlets in response. Since then, she has not aged one bit, her body
and behavior frozen at a state of being six years old. Cerberus, a denizen of the demon realm, extracted her from the portal upon sensing her fear, thus becoming her servant and guardian. Fearless and strong to the core, she is thoughtful and considerate of others, but while she doesn't show it on her face, she also craves attention and is emotionally dependent on others to a large degree.
Upon first meeting Lymle, a doubting Faize initially believed Ghimdo jested when he spoke of Lymle's symbology, and she hemceforth regarded the Eldarian as her rival.
In Lymle's ending, which is obtained if Lymle has a suitable amount of AR toward Edge, Lymle has become a Symbology teacher two years after the events of Nox Obscurus. After her students draw symbols on the ground, she casts a spell, and the symbols turn the ground into a field of flowers. As the young Symbology students frolic in the fields, Lymle plucks a daisy from the ground, inhales its scent, and smiles genuinely, finally able to show true emotion.
A secret ending can be achieved by doing a certain amount of private actions and playthroughs. She is crying at her grandfather's grave, when a figure who resembles Faize appears and places a daisy in her hair. She then turns around to smile at him.
Lymle is the most offensively oriented of the game's three mages. She has only the most basic healing spells and no spells to revive or cure status effects. Offensively, she specializes in Fire elemental symbology but she is also proficient in Lightning and Wind symbols. She is capable of summoning her Cerberus for a variety of fire-based battle skills.
Lymle is proficient in the Artistry skill, and can draw symbological Cards and Charms.
