Akimoto serialized the romantic comedy manga in LaLa magazine from June 2020 to May 2023. Hakusensha shipped the sixth and final volume in September 2023.

Synopsis
Wealthy, handsome, and successful, Arthur Louis Zetes is no stranger to the greed of people. Constantly doubting those around him, he has no faith in humanity; thus, he makes a request for the perfect maid—a robot maid. However, his butler is unable to acquire such a servant due to technological limitations, so he finds the next best substitute.

Marie Evans is a former child prodigy in martial arts known for her lack of expression. Drowning in debt, she readily accepts the offer to be a maid that acts like a robot. While Arthur is often blunt towards humans, he cannot help but dote on his personal robot; in turn, Marie is moved by his drive and consideration toward her.

Kikaijikake no Marie follows the comedic everyday life of a rich heir and his mechanical (human) maid. [Written by MAL Rewrite]
