Mary is a central figure in the anime Moonrise, originating as one of the artificially created SEEDs, beings developed by the artificial intelligence Sapientia as part of a project to colonize the Moon. She is closely tied to the enigmatic L-Zone, an experimental organism that later becomes a destructive force enveloping the lunar surface. Mary falls into a comatose state and is taken by the L-Zone to the top of a tower, where she remains in suspended animation for much of the story. Her personality is conveyed through moments of direct confrontation, as she does not hesitate to speak her mind and challenge others, particularly the protagonist Jack, when she disagrees with their actions or understanding of the conflict. Her core motivation appears tied to survival and the protection of the Moon's inhabitants, though her deeper connection to the L-Zone suggests she may serve as a vessel or anchor for that entity. Mary’s role in the narrative is pivotal: she is the key to ending the L-Zone crisis. Her unique biology, sharing certain particles with Jack, allows the two of them to freeze and destabilize the L-Zone when their abilities combine. Her awakening from the coma, prompted by Jack’s request, miraculously neutralizes the L-Zone entirely. Key relationships include Jack, who works to reach and save her; Rhys, a member of the VC3 squad who attempts to assassinate her and later wanders the Earth in guilt; and the L-Zone itself, which seems to respond directly to her presence. Over the course of the story, Mary progresses from a passive, comatose figure into an active agent whose conscious choice resolves the greatest threat of the series. Among her notable abilities are the aforementioned particle-based power that counters the L-Zone, as well as an inherent bond with that entity that drives its behavior and movements.
