Narcissu Side 2nd is a free visual novel by the dōjin group stage-nana, telling the story of a terminally ill young man and woman.

Originally, the story of “Narcissu” was written by Tomo Kataoka in 2005 and released for free download on the web. Mr. Kataoka has been exceedingly generous in allowing fans across the globe to translate these two games, on the condition that they be released for free just like the originals were. Thanks to that, the original game has been translated into a number of languages, including English , French , and Chinese . Anyone who is interested in bringing this story into other languages is encouraged to give it a try, and the translation community would be happy to help. (Source)
