Meia is a young woman with long, black hair who wears a white bustier covered by a revealing and stylized blue cloak. Her left arm is fashioned with armor and a pauldron while her right arm is distinguished by a pinwheel bracelet. She wears grieves.
During her appearance in the Battle Tower, she is cloaked in a blue robe that conceals her appearance.
Due to her status as heretic like Garland, Vox orders the blanks to slay Meia. Vox deduces her heretic status by associating her sea breeze scent with being a minion of Chaos, as the sea is Chaos's domain. However, she also possesses the ability to see Echo, a feat only available to outsiders like Wol who do not hail from Palamecia.
Meia meets Wol as he ascends the Battle Tower to find Voyd's murderer. While under attack from Omega, the blank confronts the blue witch about her role in Voyd's death, with Meia admitting that she had no choice but to eliminate him as an act of self-defense. Citing Voyd as representative of Palamecian rule, she considered him a threat to her plans. Meia then summons monsters to hinder Wol but fails in that he defeats all of her creatures. Following his dispatch of her monsters, Wol chooses not to slay Meia.
After her defeat, Meia grows stronger thanks to Wol's efforts. She decides to place a curse on him so that he may never forget her, during which she tells him of her name. Following this encounter, Meia decides to work with Echo to summon beasts and creatures for Wol to conquer.
