## History
### Members

The group was formed by veteran singer and then-I've Sound vocalist Eiko Shimamiya, who also served as their vocal coach, in 2010. The first of the group to debut was Airi Kirishima, in the middle of 2009, when it was announced that she would perform the song "Two heaRt", the opening song of the game "Futa-Ane". The song was written by Maiko Iuchi of I've Sound and the lyrics were written by Kotoko. Since then, she performed another solo song titled "Kizuna-Endless days". The song was included in Extract, I've Sound's 7th compilation album.
In 2010, the second Larval Stage Planning member, Nami Maisaki, debuted. Her first song was "Piece of My Heart", which was an insert song used in the eroge Koi to Senkyo to Chocolate. The lyrics were written by Mami Kawada and was composed by Tomoyuki Nakazawa. The last member, Rin Asami, was previously a model signed to the agency Realize, and wanted to become a voice actress, but decided to take up singing instead. In 2011, she released her debut solo song, "Lead to the smile", which was written by Kawada and was the opening theme of the visual novel Toraba. In November of the same year, it was announced that she would be the first among the group to release a single. The single, titled "Got it!", was released at Comiket 2011.
