Ogenki Clinic

Ogenki Clinic (お元気クリニック Ogenki Kurinikku?) is a 1987 hentai manga series by Haruka Inui which was originally published in Play Comic. The manga was adapted into an anime OVA series. There was also a live-action version, Welcome to Ogenki Clinic. The plotline revolves around the quirky (and perpetually horny) Doctor Sawaru Ogenki and his beautiful nurse, the busty Ruko Tatase, who help patients through their problems, and the cure almost always involves sex (something Ogenki doesn't approve on too well).

Ogenki Clinic is a comedic hentai that often employed visual metaphors for the doctor's cures. Referring to sexual intercourse as a game of pinball, or illustrating a penis as an actual missile or gun are just a few examples of the manga's humorous scenes.

It was later adapted into an anime OVA series.


 * Cerberus Syndrome: While it never stops being comedic entirely, the chapters that focus on or mention AIDS are demonstrably more serious in tone than the rest by a considerable degree, with Ogenki even giving sane, sensible advice on how to prevent contracting HIV in utter seriousness at one point.
 * Germans Love David Hasselhoff: Many characters who are Japanese are massive fans of Americans, who, while popular in their own countries, are damned near worshiped by their Japanese fans, such as Ogenki's fanatical Perverse Sexual Lust for Marylin Monroe, to the point he literally creams himself when.
 * Footnote Fever: Quite a few footnotes can be found in the scanlations, and even the official versions of the manga.
 * Gag Penis: Quite a few. And some even have faces and are treated like actual characters.
 * Loads and Loads of Characters: To the point there is brief quiz in one chapter asking if the reader can remember who at least a dozen are.
 * Harem Comedy: The series has a lot of this with the recurring characters, though most are eventually paired off with someone on a permanent basis (though given the amorous nature of the cast, this doesn't mean total monogamy).
 * Morally-Ambiguous Doctorate: Sawaru Ogenki might be a shameless hedonist (partially because it's his job), but genuinely does want the best for all of his patients, takes his professional responsibility quite seriously when the plot dips into its rare serious moments, quite seriously recommends getting complete medical testing in case of worries about getting STDs with one's partner, and firmly supports sexual activity so long as its between consenting parties who aren't committing acts that violate any laws.
 * On the other hand, Dr. Kaoriko Ayashibana is slightly less scrupulous, being a rival to Ogenki with a clinic in the same building, and is not above attempting to sleep with him to compromise his own business..
 * No Fourth Wall: The fourth wall is frequently gazed at by the characters, many of which refer to the audience and certain chapters by number when need be.
 * Porn With Plot: And amazingly consistent continuity as well.
 * Sick and Wrong: Played with. While the series portrays a lot of sexual deviancy and fetishism, the official position of Ogenki himself (who sets the tone of the plot) as that none of this is actually this trope unless it leads to socially undesirable activity like crime or compromises the person with the deviancy to integrate into society, and his goal is to refocus these behaviors into a form that falls outside the series definition of this trope.
 * The Anime of the Manga: Which is even referenced in the manga itself.
 * Slap Slap Kiss / Kiss Kiss Slap: The relationship of a lot of characters, especially those into BDSM, seesaws between these tropes.
