What the game is
Detective Masochist is a hentai visual novel for Windows, built around a femdom storyline. Its Nutaku page names U+Me PLUS as both publisher and developer, and lists English as the language. It is sold as a download for a one-time price, and the MangaGamer page lists it with female full voice. The MangaGamer page for the same game gives the longer title Detective Masochist -The Case of the Femdom Torture-.
The premise fits in 2 sentences. An aspiring detective stuck in a stale career wishes for success, and a mysterious stranger grants the wish with a catch: his childhood friend Satomi turns into a sadistic domme. A reader who wants a story about a dominant heroine, a masochist narrator and a friendship under strain will know from that whether the game is for them.
How it plays
The game is a visual novel, so the player reads and follows a story; despite the title, neither page describes a case-solving system. The protagonist is an aspiring detective who longs for success in his career. He spends his time with Satomi, who takes care of him as well as a best friend can. The page sets the two against each other: his existence is a struggle, while she is described as brilliant with a bright future, and her loyalty to the friendship is called solid. His wish for a successful career is answered by the stranger, who adds a twist, and Satomi's mild-mannered side gives way to a persona that revels in tormenting and teasing him. The page describes the relationship as plunging to new depths of sado-masochism.
The page also describes the protagonist as succumbing to her coercions while wondering what will become of the friendship if he ever manages to reverse the curse. That is the tension the story is built on. The wish, the curse and the stranger are the story's setup, and the page presents the curse as something the protagonist might undo, which makes the question of whether he wants to part of the drama.
The Nutaku page calls it a multi-layered story and a rich visual novel for femdom masochists. That is the publisher's claim, and the page adds that the turn of events proves both a blessing and a curse for the protagonist. Neither page states a play time or a number of endings.
The MangaGamer page fills in the cast. Satomi Komatsu is described as bright, friendly and fond of cute things, who has a slight complex about being tall, has known the hero for years, is mildly appalled by his lifestyle yet still helps him out in any way she can, and has a hard time talking about matters of the heart. The same profile says she fails to see how close the two of them are, though everyone else can. Sonoko Nomi is a prim and proper lady from a well-to-do family, with a strict upbringing, a slight smile and a frankness that can land on a person's insecurities without her noticing, which is why the profile says others find her hard to approach. Subaru Nonoichi is an athletic character who is always in motion, who often turns up at the detective office, and who sees the hero as a rival for Satomi's attention and tries to punish him with head and leg locks. The Nutaku page tags the game with Leg Lock, which matches that description. The detective's office is the setting the page names for these characters.
The MangaGamer page lists the voice as female full voice, so the female cast is voiced in full. That page is also split into Synopsis, Characters and Reviews tabs, and it files the game in its Nukige section.
Content and themes
The Nutaku page lists the genre as Visual Novel and the tags Hentai, Femdom, Futanari, Giantess, Transgender, Uncensored, Twintails, BDSM, Footjob and Leg Lock. Its key features read Sex version Visual Novel, Uncensored 18+ scenes, Femdom Storyline and Futanari character.
The BDSM and femdom content is the premise itself: a dominant heroine and a masochistic male narrator, with sado-masochism named as the direction of the relationship. The Futanari and Transgender tags and the feature line naming a futanari character cover the game's gender-diverse content, and MangaGamer repeats Futanari among its categories. The pages do not say how that character figures in the plot, so the tags are all a reader has to go on. Nutaku calls the game a hentai visual novel, and the tags Twintails and Giantess name visual traits of its anime-style cast.
Uncensored is listed as a tag and as a feature on Nutaku, and the MangaGamer page lists the rating as without mosaics. Both stores agree on that point.
Platforms and where to get it
The Nutaku page lists Windows Desktop as the platform and gives a download size of 771.29 mb. It lists English as the language. The MangaGamer page lists Windows 10, Windows 8, Windows 7, Windows Vista and Windows XP. Windows is the only system either page names.
The 2 places to get the game are Nutaku and MangaGamer, both download stores with accounts. MangaGamer sells it as a digital download and asks for a date of birth before showing the page.
Price and model
Detective Masochist is paid for once, per store, and then downloaded; neither store attaches a subscription or supporter tier to it. As of October 2026 Nutaku's buy button shows $15.00 and MangaGamer's price line shows $14.95. No sale price appears on either page.
Development state and version
Both stores present a finished release. In October 2026 the Nutaku page gives the version as 2 and a release date of October 12, 2016. The MangaGamer page, read the same month, gives an on-sale date of Aug 26, 2016 for its listing. It names the developer as UMe SOFT and the publisher as U+Me PLUS, while the Nutaku page names U+Me PLUS for both. The pages do not explain the difference.
Who it suits
This suits a reader who wants a femdom visual novel with a clear premise, a masochist narrator, a voiced cast and uncensored scenes on Windows, and who is content with a story the page describes only in outline. The MangaGamer list of supported Windows versions also helps a reader on an older machine.
It suits less a reader who wants a game that runs outside Windows, or who needs a stated play time before buying. The caveat is the thin description of structure, and the reader should expect a focused visual novel rather than a detective game with investigation mechanics.
