From MangaHelpers:

Ichijo Kazuya thought that he was murdered, but when he came to, he was back in his high school days. He lived his entire life as a playboy and had had countless sexual encounters with women until that fateful day that he was killed.

Taken back 15 years into his past, it seems that he has been given a second chance at life and given a chance to make different choices. He decides that the way to prevent his eventual demise is to make sure Masaki is more successful with girls and loses his virginity before Kazuya.

From MangaHelpers:

Nogawa Izumi is a good student, and a class representative, but she has an increasingly high libido. It's gotten to the point that she'll claim to feel bad during class, so she can run to the nurse's office and masturbate. When she learns that the Earth is being invaded by aliens that look like people dressed up as animals, it turns out her high sex drive may be able to help protect the Earth. The first time Izumi is attacked by the aliens, she is rescued by Usayama, a bunny alien whose race was their previous victim. Usayama gives her an outfit (a sexy swimsuit) that will allow her to fight the aliens, but which also sends her constant arousal through the roof. The scientific organization that Usayama is affiliated with think that Izumi, with her high erotic level, may be the person they've been looking for to fight the aliens. Will Izumi be able to save the Earth? [tethysdust]

From Dark Horse:
Deep into the twenty-first century, the line between man and machine has been inexorably blurred as humans rely on the enhancement of mechanical implants and robots are upgraded with human tissue. In this rapidly converging technoscape, the covert-ops agents of Section 9 are charged to track and crack the most dangerous terrorists, cybercriminals, and ghost hackers. And speaking of ghosts, when supposedly dead people start turning up walking and talking, Section 9 begins to look into the possibility that corpses are being "puppeted" from a remote location, and some serious powerbrokers may be pulling the strings.
Ghost in the Shell 1.5: Human-Error Processor presents for the first time in America the "lost" Ghost in the Shell stories, created by Shirow Masamune after completing work on the original Ghost in the Shell manga and prior to his tour-de-force, Ghost in the Shell 2: Man-Machine Interface, but never collected until now. Focusing on Section 9 agents in their daily battle against technocrime, Human-Error Processor has all the mind-twisting cybermadness you've come to expect from Ghost in the Shell, but set in a more police-procedural context with action and suspense galore.
