The series is licensed by Yen Press in English, with the first volume published in August 2025. They describe the series as follows:

He was a boy. She was a girl…Can it be any more obvious? Actually, he’s not just a boy—he’s Arthur Louis Zetes, heir to the mega-rich Zetes conglomerate and a guy who absolutely despises humans. And so the powers that be had the wonderfully sane idea of hiring martial arts prodigy Marie as a robot maid and bodyguard against those with nefarious intentions for quite a tidy sum. Which is cool and all, except they forgot to mention one teensy, tiny detail…This guy dotes on inanimate objects like Marie can’t believe, so now she’s not sure which will kill her first—the assassins or his affections?!
