Hentai Anime Girl

The Lolita Anime series was the first hentai original video animation (OVA), released in 1984 by Wonder Kids, which mainly focused on underage sex, rape, and bondage. Cream Lemon, which contained many themes found in hentai today, was released later that year by Fairy Dust and contained some in-depth storylines and classic (late 1970s to early 1980s style) artwork. The Brothers Grime was a three-video cartoon-pornography series produced by Excalibur Films in 1986, 1987, and 1988, using titles primarily from the Cream Lemon series, the most popular of Japan's erotic anime before Urotsukidoji.
The Urotsukidoji anime series was created by Toshio Maeda in 1986 and released in America in 1992 by Anime 18. It is most famous for being the first in the tentacle rape genre, though only one scene in the first OVA actually contains any tentacle rape. Tentacle rape was not present in the Urotsukidoji manga, but was featured in a series that he would publish years later called Demon Beast Invasion. Demon Beast Invasion created what might be called the modern paradigm of tentacle porn, in which the elements of sexual assault are emphasized. Maeda explained that he invented the practice to get around strict Japanese censorship regulations, which prohibit the depiction of the penis but apparently do not prohibit showing sexual penetration by a tentacle or similar (often robotic) appendage. Maeda went on to create La Blue Girl, which departs somewhat from its predecessors by lightening the atmosphere with humor, lightly parodying the tentacle rape genre.
In November 1994 A.D. Vision released their first title, The Legend of Lyon, under its hentai label, Soft Cel Pictures. A.D. Vision put out 19 Soft Cel Pictures releases during 1995 and 12 through the first half of 1996, some of which were rereleases of previous A.D. Vision Films titles in their unedited form. Soft Cel Pictures shut down in 2005 and most of its titles were acquired by Critical Mass.
Critical Mass was created in 1996 when The Right Stuf made a deal with Manga Entertainment to release an unedited edition of Violence Jack, which they deemed too intense for their normal line. Critical Mass has since released a large number of hentai titles. Most of their titles are associated with The Vanilla Series, a series of hentai titles produced in Japan by Digital Works which are tied-in with eroge games of the same title. When Central Park Media went bankrupt in the year of 2009, the licenses for all Anime 18-related products and movies were transferred to Critical Mass.
