Is Hentai Prince and the Stony Cat Manga Finished?

If you’ve been wondering whether the manga version of Hentai Ouji to Warawanai Neko — also known as The “Hentai” Prince and the Stony Cat — ever reached a proper conclusion, the short answer is: yes, it’s done. The series wrapped up completely, and you won’t be left hanging on a cliffhanger or an indefinite hiatus.

Before we go further, a quick note about the title: despite the word “Hentai” in the name, this is not explicit or pornographic material. In context, “hentai” is used in its everyday Japanese meaning of “pervert” — referring to the main character’s personality, not the genre. The series carries a 16+ age rating and contains comedic fanservice (meaning scenes designed to be playful or titillating rather than to advance the plot), but it’s a romantic comedy at heart, not adult content.

There is one major caveat English-speaking readers need to know upfront: only the first 3 of 8 volumes were ever officially released in English, and those are effectively out of print (meaning the publisher is no longer producing new copies, making them difficult to find through normal retailers). If you can only read in English, this directly affects whether investing in this series makes sense for you — and we’ll cover your alternative options below.

Let’s break down everything about the manga’s status, how many volumes exist, and what the full English availability situation looks like.

Yes, The “Hentai” Prince and the Stony Cat (Hentai Ouji to Warawanai Neko) Manga Is Finished — Final Volume Released March 2018

The manga is complete. It ended with volume 8, which was released on March 23, 2018, in Japan. There are no more volumes coming — the story reached its conclusion.

The series was serialized in Monthly Comic Alive, a Japanese magazine that published new chapters on a monthly schedule before they were collected into book-format volumes. The volumes were released under the MF Comics Alive Series label by KADOKAWA, a major Japanese publisher. The manga is based on the original light novel by Sou Sagara — a light novel being a short, illustrated Japanese novel typically aimed at a young adult audience. The manga artwork is by Okomeken, with character designs by Kantoku.

Genre-wise, this is a supernatural romantic comedy with harem elements — “harem” meaning the story follows one main character who is romantically involved with or pursued by multiple love interests at the same time. The premise revolves around a cat statue that can take away or grant personality traits, leading to all kinds of comedic and romantic chaos. If you enjoy stories where a magical gimmick throws characters together and forces them to be emotionally honest (sometimes literally), this one delivers on that concept across its full run.

Does the Romance Get a Proper Ending?

This is the question that matters most for romance readers, and the good news is that the manga does provide a defined endpoint. Across its 8 volumes, the story builds a complete narrative arc — meaning there is a beginning, a middle, and a clear resolution rather than an unfinished storyline. You’re not getting a situation where the manga stops abruptly and expects you to pick up another format to find out what happens. The manga wraps up its storyline on its own terms.

Without spoiling specific plot points, the series balances its supernatural comedy with genuine romantic development between the leads. The harem elements mean there are multiple girls involved, and the humor leans heavily on misunderstandings caused by the cat statue’s powers. But underneath the comedy, there’s a consistent thread of the main characters learning to express their real feelings — which, given the premise (a statue that literally removes your ability to show emotions), makes for a surprisingly fitting romantic payoff.

The main character does reach a clear romantic resolution by the end of the series. If you’re coming to this as a romance reader who wants closure: the manga gives you an ending where feelings are addressed and a direction is chosen. Whether you personally find that resolution satisfying will depend on which characters you connect with most, but narratively, the story commits to its conclusion rather than trailing off into ambiguity.

How Many Volumes Are There and What Does a Complete Set Look Like?

The complete manga run is 8 volumes, all published in Japanese under the MF Comics Alive Series (KADOKAWA). A manga volume is a book — usually around 180–200 pages — that collects several chapters of the story that were originally published individually in a magazine. Both print and digital editions are available for the Japanese release.

Here’s where things get complicated for English-speaking readers:

Digital Manga Publishing (DMP), a Western company that licensed manga for English-language release, published volumes 1 through 3 in English between November 2012 and July 2015. And then they stopped. The remaining five volumes (4 through 8) were never officially translated into English. The three English volumes that do exist are effectively out of print.

This means a “complete set” in English simply doesn’t exist through official channels. If you want to read the full story as the creators intended it, you’re looking at the Japanese edition for the complete 8-volume run.

The English volumes carried a 16+ age rating, which gives you a sense of the content level — it contains fanservice and mature comedy typical of the harem romantic comedy genre, but it is not explicit material.

For readers who want to own the Japanese volumes, digital editions through KADOKAWA’s platforms are likely the most accessible route. The physical Japanese volumes may require importing through retailers that stock Japanese manga.

The Original Light Novel and Anime Adaptation

The manga doesn’t exist in isolation — it’s one of several ways this story has been told across different formats. Understanding these options can help you decide the best way to experience the story, especially if the English manga availability is a barrier for you.

The Light Novel: The original source material is a light novel series written by Sou Sagara. A light novel is a type of Japanese novel — shorter than a typical Western novel, often illustrated, and aimed at young adult readers. The light novel has its own volume numbering that is separate from the manga. The light novel goes deeper into the source material and may cover plot points or character details that the manga condenses or skips.

The Anime: A TV anime adaptation — anime being Japanese animated television — aired starting April 13, 2013. For romance fans who can’t access the full manga in English, the anime offers another way to experience the story. However, anime adaptations of light novels and manga frequently cover only a portion of the source material rather than the entire story. It is common for a single-season anime to adapt only the early volumes of its source, leaving later plot developments — including romantic conclusions — uncovered. Keep this in mind if you’re considering the anime as a substitute for the complete manga: it may not reach the same ending the manga does.

For romance readers specifically: The manga stands on its own as a complete 8-volume romantic comedy. You don’t need to read the light novel first, and you don’t need to watch the anime to understand the manga. Each format tells the story in its own way. That said, if you enjoy the characters and want more, the light novel and anime are there as supplementary options — with the anime being particularly useful for English-speaking readers who want at least a partial experience of the story without needing to read Japanese.

Where to Start Reading

If you’ve decided to read the manga, the reading order is simple: volume 1 through volume 8, in order. There are no side stories that need to be slotted into the main reading order, and no separate volumes required to understand the plot. It’s a single, straightforward series.

The original light novel can be read separately if you want to experience the source material, but it isn’t required to follow or enjoy the manga. Think of it as optional extra context rather than required preparation.

A practical note on English availability: Since only the first 3 volumes were ever officially released in English — and those are no longer in print — most readers encountering this series today will need to read it in Japanese to experience the full story. If you don’t read Japanese, here’s an honest assessment of your options:

• The anime adaptation gives you an animated version of at least part of the story in Japanese with potential subtitle availability. As noted above, it may not cover the manga’s full storyline or ending, so set your expectations accordingly.
• The first three English manga volumes give you the opening portion of the story, though finding copies may require searching secondhand markets since they’re out of print.
• The Japanese manga (print or digital) is the only way to read the complete story in its original manga form.

For those who do read Japanese or are learning, the manga’s comedic tone and relatively straightforward dialogue make it a manageable read compared to more text-heavy manga. The 8-volume length also means it won’t take forever to get through the complete story.

Frequently Asked Questions

Is the manga the same as the light novel?

No. The manga is an adaptation of the light novel — meaning the manga retells the light novel’s story in a visual, comic-style format with panels and artwork. The light novel is the original work written by Sou Sagara, while the manga was illustrated by Okomeken. While they follow the same core story, they’re separate publications with different volume counts and different levels of detail. The manga condenses and visualizes the light novel’s narrative, but they aren’t interchangeable — each offers a distinct reading experience.

Will there be more manga volumes?

No. The manga concluded with volume 8 in March 2018, and the series is listed as complete. There are no announcements of continuation, sequel chapters, or additional volumes. Eight volumes is the full and final run.

Can I read the full series in English?

Unfortunately, only volumes 1 through 3 were officially released in English by Digital Manga Publishing. Those releases happened between 2012 and 2015, and DMP never continued past volume 3. The existing English volumes are no longer being manufactured by the publisher, making them hard to find through standard retailers. The remaining five volumes (4–8) have never received an official English translation.

If reading in English is important to you, the anime adaptation offers an alternative way to experience at least part of the story, though it may not cover the manga’s complete storyline or ending. For the full manga experience from beginning to end, the Japanese edition — available in both print and digital formats — is the only option through official channels.

What does “Hentai” mean in the title?

The word “hentai” in the title does not refer to the adult content genre. In Japanese, “hentai” can simply mean “pervert” or “weirdo,” and that’s how it’s used here — it describes the main character’s personality. The series is a romantic comedy rated 16+, not adult material. The quotation marks around “Hentai” in the official English title are there specifically to signal that the word is being used as a character descriptor, not a genre label.
