Mechanical Marie Story Synopsis
The Mechanical Marie anime is based on Aki Akimoto’s manga series, which was initially a one-shot published in Hakusensha’s LaLa magazine in March 2020, before being serialized from June 2020 to June 2023. A sequel series titled Mechanical Marie+ began serialization in LaLa in April 2025.
The story revolves around Marie, a human girl who was once a genius martial artist. To hide her true identity, she takes on the role of a “mechanical maid” in the mansion of Arthur, an heir to a powerful conglomerate who harbors a strong dislike for humans. Marie’s naturally expressionless face aids her in maintaining her robot disguise, allowing her to flawlessly carry out her duties. All the while, she secretly protects Arthur from constant assassination attempts. The plot is further complicated by Arthur’s strong affection for Marie, which frequently puts her human identity at risk of exposure, leading to a series of comedic and tense situations.
