Adventure Kid (Japanese: アドベンチャーKID, Hepburn: Adobenchā Kiddo) is an erotic manga series written and illustrated by Toshio Maeda.

In the British release of the anime the alternate name Adventure Duo was used because it was believed parents might buy it for their children by mistake without realizing the explicit sexual content and scenes of tentacle rape.

They meet some friends including a sexy elf woman named Eganko who falls in love with Norikazu, and a perverted monster prince who is soon enslaved by Midori.

In doing so, they witness the atomic bomb being dropped on Hiroshima, and there is an appearance of the Enola Gay, as well as numerous symbols of Japanese culture at the time.

Mariana Ortega-Brena, writing in the journal Sexuality & Culture, classified it as "situated somewhere between porn, sci-fi horror and the slasher film" with a darker tone than regular hentai.

[4] Helen McCarthy in 500 Essential Anime Movies called it "an insane mixture of pornography and sitcom,"[6] while Sequential Tart's Sheena McNeil affirmed it is "erotic fantasy with a good dose of humor.

[1][2] Chris Beveridge of Mania.com compared the Hiroshima scene to the style of the film Dr. Strangelove and said there was an "almost outright theft" of Terminator 2: Judgment Day's main theme by Brad Fiedel.

[7] Clements and McCarthy wrote that it adds a sexual content on the "alien girlfriend-squatter set-up of Urusei Yatsura" and found humorous references condemning the excesses of the author's previous work, Urotsukidōji.

[10][11] A three-episode original video animation (OVA) titled Yōjū Sensen Adventure Kid[note 1] was directed by Hideki Takayama.

[7][13][note 2] Originally the production staff wanted to have live-action erotic actresses dubbing some characters to create a public appeal but with no background on it the hired cast was not able to act.

"[24] Allen Divers, writing for Anime News Network, reviewed the third volume of the manga and said that "Adventure Kid is a well drawn tale with a variety of sight gags and quite witty dialogue.
