Narcissu -Side 2nd- is the prequel to the visual novel Narcissu, produced by Stage-nana. A preview version was sold at Comiket 70 for ¥200, and has since been released for free download. On May 15, 2007 the entire game was released and made available for download on stage-nana's website. The English version was released on March 31, 2010 by Agilis, after "close to 3 years of blood, sweat, and hard work." Like the Japanese version, this release contains both the prequel and the original. The translation was done in Proportional ONscripter, a fork of ONscripter and a clone of Nscripter, which supports English text as opposed to Nscripter which in turn, doesn't. Additionally, Side 2nd includes both games' soundtracks accessible from the menu of the game.
