Aki Akimoto’s hit romantic comedy “Mechanical Marie” is getting an anime adaptation, set to air in Fall 2025! A teaser visual and teaser video have been released, along with the announcement of the lead cast: Nao Toyama as Marie and Haruki Ishiya as Arthur. Both voice actors have also shared their thoughts in special comments. Additionally, a congratulatory message from the original creator, Aki Akimoto has arrived.

“Mechanical Marie” is a heartfelt romantic comedy about Marie, a former genius martial artist with a stoic demeanor, and Arthur, the heir to a massive conglomerate. Due to certain circumstances, Marie serves Arthur as a “mechanical maid,” despite being human. As she protects Arthur from daily assassination attempts, the story unfolds with both laughter and emotional moments.

The newly revealed key visual features Marie and Arthur side by side, capturing a moment where the human-averse Arthur lowers his guard only around Marie. The teaser video, the first animated footage of the series, shows Marie nervously navigating her days under the premise of “never letting anyone know she’s human.”
