愛欲幻想の怪～クトゥルフ・プレグナント～ (The Mystery of Lustful Illusion -Cthulhu Pregnant-) by Takayuki Hiyori (宇行 日和) is a 2015 Japanese tankōbon hentai manga published by Unreal Comics (アンリアル). This book is divided into ten chapters, each of which contains a fully-illustrated and sexually explicit Cthulhu Mythos story.
In art style, the book is geared more toward erotic comedy than erotic horror; and many of the Cthulhu Mythos entities within are presented as monster girls. Takayuki Hiyori had been previously known for their dōjinshi based on popular monster girl harem manga Monster Musume, and their manga are essentially a pornographic parallel to the mostly non-explicit books like Monster Girl Encyclopedia II (2016) by Kenkou Cross (健康クロス).
In terms of writing and storytelling, The Mystery of Lustful Illusion -Cthulhu Pregnant- is a disconnected collection of short works, much like most Lovecraft story collections or Lafcadio Hearn’s classic collection Kwaidan. There is no larger overarching story of narrative, the major appeal of the work being simply that it uses the Cthulhu Mythos for these erotic stories and sexualized versions of eldritch entities like Cthulhu, Hastur, Shub-Niggurath, the Deep Ones, the Hounds of Tindalos, and the Cats of Ulthar.
The contents are aimed toward some well-established tropes and kinks: as the title might imply, impregnation is a fairly significant theme in many of the stories, but there are also instances of multiple penetration, sex work, incest, nonconsensual sex, body transformation or modification, breast expansion, group sex, large genitals, etc. Readers familiar with tentacle erotica might wonder if such appendages play their part, as they do in Le Pornomicon (2005) by Logan Kowalsky, but in truth they don’t play a significant role in the proceedings.
In point of fact, The Mystery of Lustful Illusion -Cthulhu Pregnant- is difficult to distinguish from Monster Musume or Monster Girl Encyclopedia products. While Takayuki Hiyori uses references to the Cthulhu Mythos in the crafting and telling of the stories, the manga itself is pretty straight forward monster girl erotica, and aimed more directly at that audience than Lovecraft fans. The depictions of the various Mythos entities is mostly original, but skewed toward “mostly human with a few non-human traits”—the Cats of Ulthar, for example, are indistinguishable from the generic manga or anime “catgirl,” with their primary feline traits being cat ears and tail on a nubile young woman’s body. Eldritch horrors are hinted at but seldom realized.
The contents of this book might be generally compared to the more sexually explicit chapters of The Elder Sister-like One by Pochi Iida (飯田ぽち。), but where Pochi is telling an extended narrative with a few characters with extended character development and exploring emotions, Takayuki Hiyori is necessarily more episodic, with varied content and swift-moving stories that tend to get to the sexual action fast, dwell on them for the majority of the length of the chapter, and come to a relatively swift conclusion.
Arguably the most fun chapter in the book is a variation on “The Cats of Ulthar.” While the forms the cats take are stereotypical for hentai manga, and the results are pretty much what you might expect, it both pays homage to Lovecraft’s original work while playfully subverting aspects of it. One might compare it in some ways to the “erotic” versions of classic horror novels which achieved a bit of notoriety in the 1970s, like The Adult Version of Frankenstein and The Adult Version of Dracula by “Hal Kantor” (Ed Wood, Jr.). Erotic retellings of Lovecraft aren’t exactly new—for example, “Herburt East: Refuckinator” (2012) by Lula Lisbon—but illustrated or graphic adaptations are relatively scarce.
愛欲幻想の怪～クトゥルフ・プレグナント～ (The Mystery of Lustful Illusion -Cthulhu Pregnant-) by Takayuki Hiyori (宇行 日和) has not been officially translated into English or published in the United States; perhaps some company like FAKKU might do so in the future and make it more widely available. Until then, those interested in the Japanese original can still find copies available from retailers online.
