This song is Hachi's fourteenth upload; it has entered the Hall of Legend. The song is a remake of Aldebaran and Träumerei, two previous non-VOCALOID songs by Hachi. The pair of songs were designed as a pair, with one cheerful while the other dark. Hachi was inspired by Hayao Miyazaki's ambiguous endings and, as a result, intended the song to have various interpretations similar to Miyazaki's work.
