An heiress to one of the largest conglomerates in Japan is perfect in public and in private doesn’t even know how to take care of herself. That is the premise of Rich Girl Caretaker, which has just released its second trailer, adding Kentaro Kumagai to the cast and confirming its premiere for . The series will reach Crunchyroll in multiple regions of the world. The new trailer expands the look at the characters and their dynamics, building on previous promotional material with a direct focus on the central caring relationship between the protagonists.

is performed by angela, while the ending Kanpeki Janai Watashi
is performed by Ami Maeshima, who is also part of the voice cast.
It’s a Study in Catastrophic Dependence
Let’s cut through the noise. The premise isn’t merely a rich-girl trope. It’s a study in catastrophic dependence. Hinako Konohana, the perfect public heir, is privately incompetent. She doesn’t have a few rough edges; she’s fundamentally unequipped for basic existence. That’s not a charming quirk. It’s a character study in fragility. The new trailer doesn’t just show this; it frames it as the engine of the entire narrative. The central relationship—caretaker and charge—is built on a secret, which is always a potent accelerant for character dynamics.
Voice Cast
New addition:
- Kentaro Kumagai as Katsuya Taisho – previously Hanma Yujiro in Baki Hanma and Suo Hayato in Engage Kiss
Previously confirmed cast:
- Yuto Uemura as Itsuki Tomonari – previously Alus Reigin in The Greatest Magicmaster’s Retirement Plan and Tanjiro Kamado in some Kimetsu no Yaiba games
- Konomi Kohara as Hinako Konohana – previously Akane Shinjo in SSSS.Gridman and Kasumi Nomura in Asobi Asobase
- Saori Onishi as Mirei Tennoji – previously Eris in KonoSuba and Miyuki Shiba in Mahouka Koukou no Rettousei
- Ami Koshimizu as Shizune Tsurumi – previously Kallen Stadtfeld in Code Geass and Holo in Spice and Wolf
- Takehito Koyasu as Kagen Konohana – the legendary Dio Brando in JoJo’s Bizarre Adventure and Ryomen Sukuna in Jujutsu Kaisen
Casting as Architecture – Voices That Build Psychology
The casting confirms the show’s tonal ambition. They haven’t just gathered voices; they’ve hired architects of persona. Kentaro Kumagai, who voiced the terrifyingly precise Hanma Yujiro, is now Katsuya Taisho. That’s a sharp left turn, suggesting a character whose control is psychological, not physical. Pair him with Yuto Uemura, whose Tanjiro embodies earnest duty, and you get an interesting audible conflict: detached discipline versus compassionate responsibility. And placing Takehito Koyasu—the voice of iconic megalomaniacs—as the grandfather figure, Kagen Konohana? That’s a statement. He’s not there to be kindly; he’s there to represent the weight of a dynasty.
Production Team
The direction is in charge of Shusei Morishita at studio Brains Base, with Aya Yoshinaga supervising the scripts and Nao Kawashima in charge of character design. The music is composed by Natsumi Tabuchi, Hanae Nakamura, and May Kurihara, with sound direction by Takeshi Takadera.
Production Choices That Tell a Story
The production choices from Brains Base are telling. Nao Kawashima’s character design will be key. With a protagonist who must visually toggle between perfection and collapse, the art direction isn’t just pretty; it’s a diagnostic tool. We’ll be reading her state in the line of a sleeve, the posture in a hallway. The music trio behind the score is known for nuanced, emotionally precise work. Expect the soundtrack to underline the dissonance between Hinako’s public performance and her private reality—not just wallpaper it.
Source Material
Rich Girl Caretaker is a light novel by Yusaku Sakaishi with illustrations by Sakura Miwabe, published under Hobby Japan’s HJ Bunko imprint since , with eleven volumes until . The manga adaptation by Sorahiko Mizushima has six compiled volumes.
The Story
The story follows Itsuki Tomonari, a high school student who gets involved in a kidnapping incident and ends up taking care of Hinako Konohana, heir to one of the largest conglomerates in Japan. Although Hinako projects an image of a bright and charming girl, she is actually quite lazy and lacks basic skills for everyday life—something she must hide due to her family’s expectations. As Itsuki cares for her, Hinako begins to depend on him more and more, giving rise to a relationship that goes far beyond the typical dynamic between mistress and servant.
Why This Matters Beyond July
The hook isn’t the class gap. It’s the psychology of performative perfection colliding with the need to be seen. In a genre often filled with straightforward fantasies, this story uses the caretaker
dynamic to explore a form of emotional rescue. It’s less about a knight saving a damsel and more about a witness to a quietly collapsing façade.
The real question isn’t whether the hook is fresh. It’s whether the series will have the nerve to let Hinako’s dependency be unattractive, not just endearing. Will her growth require real cost, or will the caretaking itself become a comfortable cage for both of them?
Questions Worth Asking
- If a character’s entire identity is built on a meticulously maintained performance, what does genuine care even look like to them?
- In an anime landscape familiar with the
perfect on the outside
archetype, how far can a series push the private incompetence before it stops being comedy and becomes genuine pathos? - Does the casting of actors known for playing dominant, controlling figures suggest the real conflict isn’t about learning to pour tea, but about the architecture of control itself?
