Viper GTS

Story

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.

Characters

Carrera: The main character; she is a blue-haired, buxom devil with a tremendous sexual appetite. She is also the top soul-getter of the three, despite not taking her job seriously. She also doesn't like the fact that Mercedes resents her for getting more and better quality souls. She has a high libido.

Mercedes: A red-haired devil, she is Carrera's closest friend/rival. Unlike Carrera, she takes her job a little too seriously - mainly from her jealousy of Carrera's success, and as a result makes a lot of mistakes, which usually results in her returning to the underworld dejected and empty-handed. She likes to claim that her specialties range from bathroom cleaning to conquering the world.

Rati: A short, pink-haired devil. Like Carerra, she is usually successful in capturing souls and is often on the receiving end of Carrera's affections.

When Carerra failed to deliver Ogawa's soul, she was punished by being confined in a cell for five days. After Mercedes had seduced her, Rati had visited. Seeing Carrera bound up and nude, Rati then approached her and seduced Carrera herself but with bad timing, because Carrera was set free soon after and returned the favor to Rati. Rati is shown at one point wielding a type of mace in combat against heaven's guardians. She does not appear to be very adept as she is still captured.

Alphina: A blond-haired incubus (male counterpart to a succubus), Alphina is Carrera's, Mercedes' and Rati's boss. He usually stays behind in Hell to process the souls gathered into crystals, but can be summoned if no one else is there. He is also equipped with two functional penises. The angels refer to him as the "White Devil." He is the only devil shown to be adept in combat, wearing a battlesuit similar to the warrior angels. He had former relations with a consenting angel. The nature of this relationship has yet to be clarified.

Ogawa: He is the one who summons all the devils, mostly because of Carerra. He had initially obtained the ancient book to gain revenge against those who had ridiculed him. However, upon seeing Carrera, all reason left him, and he seduced her. Unfortunately, he was unprepared for her libido and was exhausted when she finished (too exhausted for her to take his soul). After Carrera had returned to Hell, Ogawa began to miss her after some time and attempted to summon her once more. However, this was during her five-day confinement, so he asked Mercedes instead.
