Hobby Japan’s HJ Bunko imprint launched the first light‑novel volume in May 2021 and released the 11th volume on 31 October.
In September 2021, illustrator Sorahiko Mizushima began an ongoing manga adaptation on Hobby Japan’s Fire Cross platform; the sixth manga volume is slated for 1 June.
Spanish publisher Monogatari Novels announced an English license for the series in October 2023 under the title Rich Girl Caretaker: I’m Secretly the Caregiver of the Most Popular Girl in This Rich Kid School. Although Amazon listed the first English volume as shipped on 3 March 2026, the title is currently out of print and the publisher’s website is inaccessible due to customs‑related delays.
Here’s a quick synopsis from the Amazon listing:
High‑schooler Itsuki Tomonari gets tangled in a kidnapping and ends up caring for Hinako Konohana, a privileged girl from a powerful conglomerate. While Hinako appears brilliant and charming on the surface, she’s actually lazy and lacking basic life skills. Family obligations force her to maintain a “perfect lady” façade at school. Determined to protect her, Itsuki steps in as her caretaker, gradually winning her affection. “Now…if Itsuki isn’t around, I’d hate it.” This love story explores a bond that transcends a simple master‑servant dynamic.
Additionally, J‑Novel Club is releasing Sakaishi’s The Holy Knight’s Dark Road in English.
