In addition, both songs were re-released in her 2003 complication album, Ho?: Horie Yui Character Best Album.

In other media
Yui Horie humorously mentioned the song, my best friend, in her radio show, Horie Yui no Tenshi no Tamago, about the selection of songs to sing in a karaoke.

brand-new communication
brand-new communication (brand-new コミュニケイション) is Yui Horie's second single album. It was released on 17 March, 1999. The specific word in the Japanese title, communication, is unique that it does not use chōonpu (i.e. コミュニケーション) as with the Japanese title of the related anime series. It is the final album released under the Pony Canyon label in Yui Horie's name. The song, Hanagara no One Piece, is included in the separately-released Kurogane Communication original soundtrack.
