A Birthday Full of Best Intentions and Unexpected Obstacles
The upcoming episode centers on Marie’s earnest efforts to celebrate Arthur’s birthday, a day he reportedly holds few fond memories of. Driven by a desire to bring him joy, Marie embarks on baking a handmade cake. However, her plans are quickly derailed by a series of unfortunate events. She finds herself clashing with members of Arthur’s fan club at school, whom she had hoped to befriend. Adding to the chaos, Noah intervenes during her baking process, leading to the cake being accidentally dropped.
Despite these numerous mishaps, Marie perseveres and manages to present Arthur with her heartfelt, handmade cake. To her delight, Arthur is genuinely pleased by the gesture. The episode culminates in a surprising turn when Arthur expresses an additional birthday wish: “I want to be your butler and devote myself to you”. This unexpected declaration further complicates the evolving relationship between the human maid pretending to be a robot and her human-despising master.
The Premise of “Mechanical Marie”
“Mechanical Marie” (Japanese: 機械じかけのマリー, Kikaijikake no Marī) is an anime adaptation of Aki Akimoto’s manga series, which was originally a one-shot in March 2020 before being serialized from June 2020 to June 2023. The story introduces Marie Evans, a former martial arts prodigy with an expressionless face, who takes on the guise of a “mechanical maid” to pay off her debts and protect Arthur, the heir to a powerful conglomerate. Arthur harbors a deep distrust, and even hatred, for humans due to constant assassination attempts by his jealous family members.
Marie’s mission is fraught with peril; if her true human identity is discovered, it could lead to her immediate execution. While flawlessly performing her duties and secretly fending off assassins, Marie finds herself navigating Arthur’s growing affection for his “perfect” maid, leading to a nerve-wracking mix of close calls and burgeoning romance. The series is lauded as a heartwarming rom-com blending laughter and tears, exploring a relationship that blossoms from a lie between master and servant.
