Rasen Kairou



A 2000 Hentai Visual Novel by age, Rasen Kairou (it can be translated as "Spiral Corridor") is a story about a pornographic site, by the creators of Muv-Luv.

University professor Yuuji Saeki has recently acquired a computer but don't knows how to operate it correctly. One day, he meets Shion Mizushiro, brother of his pupil Aoi. He gives him a note with the address of Aoi's personal website, but Saeki mistypes the address. He ends up stumbling on a adult website called EDEN. Curious, he checks what the site is about and stumbles onto something weird: EDEN's webpage and message board seem to be talking about kidnapping and training girls to be Sex Slaves, complete with a location for a cabin where their supposed last victim is at the moment.

Saeki finds the concept far from believable but investigates a nearby park as it fits the description given by users of the website. Checking abandoned cabins, he discovers to his shock that what the users of EDEN were talking about is very real: he finds an imprisoned schoolgirl who seems willing to have sex with anybody who enters the cabin. The girl offers herself to him and, suddenly overcome with dark urges, Saeki wonders if he should have sex with her or not.
