The work was originally written in Japanese by Tomo Kataoka, and subsequently localized and translated into English, Chinese, French, Korean, Russian and Vietnamese by various fan translators. Unlike most fan translations, however, this was an authorised work. The author, however, was not actively involved in the translation process as it had been the case for "True Remembrance". Both the original Japanese visual novel and its English version were released as free downloads over the Internet. The web edition of Narcissu has lower graphics and music quality, to conserve bandwidth.
