Kikaijikake no Marie is neither just a romantic comedy nor a battle manga. It is a story that depicts the awkward and bittersweet relationship between Marie, a former martial artist who serves as a robot while concealing her human identity, and Arthur, the heir to a major conglomerate who suffers from extreme misanthropy. Marie faithfully follows commands such as “Lover Mode” and “Nursing Mode” as Arthur's exclusive maid, all the while carrying the risk of immediate execution if her true identity is discovered. In front of Arthur, who only opens his heart to inanimate objects, Marie suppresses her emotions and acts as a “machine.” However, the closeness of their distance gives a premonition that they will eventually change each other's hearts, making it impossible for readers to look away from these “subtle changes.”

Marie, who looks like a delicate maiden at first glance, actually has an unconventional background as a former genius martial artist. This gap is her greatest charm. Her figure, as she brilliantly repels assassins who appear at the mansion, is truly that of an action heroine. She looks like a demure maid, but inside she is incredibly strong. Moreover, readers can't help but want to cheer on Marie's admirable devotion as she quietly and diligently acts as a “robot” without boasting of her strength. Her developing love for Arthur and her efforts to protect him, even while constantly facing the danger of losing her life, lead to a moving development that harbors genuine strength within its quietness.

In the middle of the story, it is revealed that Arthur actually knows that Marie is human. However, Arthur does not tell her, fearing that Marie will quit being his maid. Meanwhile, Marie fears that her true identity will be exposed and desperately tries to keep her secret. The fact that this setting of “both harboring secrets” is not just a romantic game but is depicted as a sincere and painful “clash of kindness” is a major highlight of this work. Remaining silent precisely because they are in love — readers will have their hearts squeezed repeatedly by this clumsy exchange.

Although Kikaijikake no Marie might seem like a shojo manga with cuteness and romantic settings at first glance, it is actually a hybrid work packed with diverse elements such as martial arts, suspense, mystery, and romantic comedy. In addition to the unique perspective of pretending to be a robot, the contrast between Arthur's past, where he can only open his heart to inanimate objects, and Marie's circumstances gives the story depth and dramatic quality. Precisely because it is not just a romance manga, it leaves a lingering impression on the reader's heart, and even after closing the page, one cannot help but wish, “Marie and Arthur, please find happiness.”
