Menoly Mallia is an Arrancar number thirty-four in Sosuke Aizen's army and one of his two assistants; the second role at his side was performed by Loly Aivirrne. Compared to her partner, Menoly is noticeably calmer and more reasonable, though she is not always capable of insisting on her own. She is devoted to Aizen, but is ready to voice an objection if she believes the lord's decision could harm him. Toward those stronger than her, Menoly feels fear, especially toward the Espada, and tries not to get involved in dangerous undertakings. At the same time she has a conscience: Loly's cruelty often confuses her, and after being saved by Orihime Inoue, Menoly begins to avoid the girl and does not want to take part in her bullying. After the fall of Las Noches, she together with Loly ends up in the hands of Yhwach's army, and later joins the Exequias.
