The anime adaptation of Aki Akimoto’s popular romantic comedy manga, “Mechanical Marie” (Kikaijikake no Marī), wrapped up its inaugural season on December 21, 2025, with an emotionally charged twelfth episode titled “Goodbye Marie.” The finale delivered a heartwarming resolution to the central romantic dilemma, as the titular “mechanical maid” Marie finally confronted her true feelings and her hidden identity, leading to a pivotal moment with Arthur, the human-despising heir she was sworn to protect.
The Premise of “Mechanical Marie”
“Mechanical Marie” introduces Marie, a highly skilled martial artist burdened by debt. She is hired by Arthur Louis Zetes, the heir to a powerful corporation, to serve as his “mechanical maid.” Arthur, having endured countless assassination attempts orchestrated by his jealous stepbrother Maynard, harbors a deep distrust of humans and relies solely on emotionless objects. Marie, possessing a naturally stoic and expressionless demeanor, must convincingly maintain the facade of a robot while secretly acting as Arthur’s bodyguard, fending off continuous threats. The romantic comedy unfolds as Arthur develops genuine affection for his seemingly perfect maid, while Marie, in turn, finds herself falling for her eccentric employer, navigating the complexities of her secret identity and burgeoning emotions.
The anime, produced by Zero-G and Liber, premiered in October 2025, quickly captivating viewers with its unique blend of action, comedy, and heartfelt romance.
A Look Back at the Climactic Season Finale
Episode 12, “Goodbye Marie,” brought the season’s central conflicts to a head. The episode saw Marie embark on a perilous mission to retrieve an antidote for an amnesia-inducing poison that Arthur had inadvertently ingested, a scheme orchestrated by Maynard. Her quest led her to infiltrate Maynard’s heavily guarded mansion, where she encountered Noah, an assassin who, despite his antagonistic role, held a complicated attraction to Marie.
Noah, recognizing Marie’s unwavering determination, ultimately sided with her, providing the crucial antidote he had prepared himself and facilitating her escape from Maynard’s clutches. The dramatic confrontation also featured the return of Marie 2, an earlier prototype that aids in defeating Maynard’s formidable mecha in a chaotic battle.
The episode’s emotional climax arrived when Marie, after obtaining the antidote, transferred it to Arthur with a poignant goodbye kiss, instantly restoring his memories of their time together. This moment paved the way for Arthur to fully embrace his feelings, declaring his love for Marie not as a mechanical servant, but as the remarkable human she truly is. He passionately rejected the notion that her initial deception was a betrayal, instead seeing it as an act of kindness that brought him happiness. The finale concluded with a deeply content Marie, finally able to openly express her joy and love, finding her smile alongside the man she protected and grew to cherish.
Fan Reception and Future Prospects
The “Mechanical Marie” anime has garnered a positive reception, particularly for its endearing characters and romantic comedy elements. Viewers praised the charming dynamic between Marie and Arthur, and the finale’s resolution resonated strongly with those hoping for a happy ending for the unconventional couple.
While the anime series has concluded its initial run, the story of “Mechanical Marie” continues in the manga world. A sequel manga series, Mechanical Marie+, began serialization in April 2025, suggesting that fans may have more of Marie and Arthur’s adventures to look forward to in the future.
