Memory Wipe Shakes 'Mechanical Marie': Episode 11 Details Reveal Devastating Amnesia Twist

The television adaptation of Mechanical Marie (Kikaijikake no Marī) is rapidly approaching its season finale. Episode 11, titled 'Forgotten Marie,' is scheduled to air on December 14, 2025, across channels including Tokyo MX and BS Fuji, and is anticipated to deliver a significant emotional turning point following the recent events at the amusement park.

The narrative immediately addresses the fallout from the high-stakes confrontation where the mechanical maid Marie and her master Arthur Louis Zetes were trapped. Arthur subsequently collapsed, having been poisoned by his treacherous stepbrother, Maynard. While Arthur survived the assassination attempt, the chemical agent has resulted in the complete erasure of all his memories concerning Marie.

The immediate and devastating consequence of this amnesia is highlighted by Arthur’s chillingly polite greeting to the heartbroken automaton: 'Nice to meet you, Marie.' This development presents the ultimate test for Marie, voiced by Nao Toyama.

Marie, a former martial arts prodigy, has been meticulously concealing her true, human identity within Arthur’s anti-human household. She must now confront the total loss of their developing connection. Arthur, voiced by Haruki Ishiya, remains oblivious to the deception that forms the foundation of their entire relationship, continuing to cherish his 'perfect' maid despite his inherent misanthropy.

Preview imagery emphasizes Marie’s rare, visible shock in response to Arthur’s detached new demeanor. This visual cue teases the immense struggle she faces to salvage their bond without compromising her non-servile identity. This pivotal episode underscores the central tension of Aki Akimoto's acclaimed manga: whether a romance built upon a profound and dangerous lie can withstand the truth of its own beginning. As the 12-episode first season concludes, Episode 11 promises the season's most poignant and perilous development, ensuring that the established blend of action, humor, and danger reaches its climax.
