It was during the eighth month of 2006 that news of a new single surfaced. This single, titled "Ko·mo·re·bi", was officially announced to be Hitomi's 5th single at the end of August, and was used as the theme song for the movie "Tegami", which features actors Takayuki Yamada, Tetsuji Tamayama, and Erika Sawajiri. Similar to her past single, "Ko·mo·re·bi" failed to chart in the Top 30 Weekly Charts, and debuted at No. 50 for its first week on the charts, only selling about 300 more copies than "Communication". In spite of this, Hitomi was chosen to be one of many artists to take part in the new tribute album for the new Death Note movie.
