Viper GTS 01-03 720p - (1995-2003 Lang: English, Japan)

Not a lot there if our looking for a thought provoking story or deep characters, but, if your looking for something to turn you on (or fap to), then you'll be satisfied. Some of the scenes didn't fit my tastes per say (futanari for example) but, the sex scenes were well done and relevant to the story and the characters were sexy so, overall, Id say its worth a watch.

Viper GTS is a three-episode hentai anime OVA series, which is based upon a popular H anime video game series by Sogna. When it was released on DVD in the US, this OVA has been edited into a film. It has been often stated to be a perverse version of Ah! My Goddess, as certain concepts are held in the same light.[citation needed] It is indicated several times in the show that the souls are only used to create crystals. Once a crystal is made, the soul is returned to its owner (suggesting that the devils may have some code of honor). It is not made clear why the demons need the crystals or why the angels do not notice the souls being returned (although it may be that the angels wanted to destroy the devils so that the world was a more peaceful place).

The plot of the series centers around three devils: Carrera, Mercedes, and Rati, who are summoned to Earth to capture souls to process into brilliant gems eventually.

As the story begins, a nerdy boy named Ogawa uses an ancient text to summon a devil to gain revenge against those who have mistreated him. When the devil turns out to be Carrera, however, he completely forgets the reason why he summoned her and instead has sex with her. He is unprepared for her hyperactive libido, though, and by the time morning comes, he is too exhausted for the devil to take his soul. After this, the upper demons punish Carrera for failing to get Ogawa's soul leading to five days of imprisonment in which Mercedes and Rati satisfy themselves with Carrera.

Meanwhile, a group of angels has noticed some lost souls on Earth. Concerned with the violation of the laws of reincarnation angels concoct a plan to capture and "purify" the devils who are stealing the souls.

Meanwhile, Ogawa misses Carrera and attempts to summon her; instead, Mercedes answers the summons and Ogawa are very upset. Mercedes are also angry that Ogawa wants Carrera over herself. Ogawa takes out his frustrations by forcing Mercedes to have sex with him, and she then returns to hell, angry and embarrassed. Ogawa tries to summon Carrera again and succeeds. The angels, however, are prepared and manage to capture Carrera after Ogawa asks her. Ogawa then summons Rati, who flies off to heaven to rescue Carrera, but is captured herself. Ogawa uses the summons a fourth time and gets Alphina, a male devil and friend to Carrera, Mercedes, and Rati. Ogawa begs Alphina to let him help rescue Carrera along with Mercedes. The climax is a battle in heaven between Carrera and Rati and their captors and Alphina, Ogawa, and Mercedes and the warrior angels. Later, the three Devils have moved in with Ogawa, and they will have multitudes of sex.

This is a great hentai. The storyline somewhat copies the anime Ah! My Goddess. Even though it only has 3 episodes its still a must watch for anyone. I wish they had more, like a sequel or something.
