Key writer/composer/lyricist Jun Maeda and former supercell guest vocalist Yanaginagi, who is more commonly known as just "nagi," have joined together to start a new project called Owari no Hoshi no Love Song (Roughly: The Star's Love Song of the End). The artwork for the project is being done by gotoP. The text suggests there will be 13 "Love Songs" in total created that create a single story on a doomed planet. A limited edition single, the contents of which are not yet revealed, will be released at Comiket 81 in December.
Nagi previously sang the Bakemonogatari ending theme, "Kimi no Shiranai Monogatari" and will also be singing the ending theme to the upcoming series Ano Natsu de Matteru. Songs that Jun Maeda has previously composed and wrote the lyrics for include the songs in Angel Beats, including the opening and ending, and the Clannad game and TV ending themes,
