The group was made up of five past and then-present members of Morning Musume and created to celebrate their 10th anniversary.
In early 2007, Morning Musume Tanjō 10nen Kinentai was made.
Tsunku, the producer of Morning Musume, stated that the members chosen symbolize the grassroots beginning of the group; how they had five members ranging in age from 14-24.
On August 8, 2007 they released a second single - which was also their last one - "Itoshiki Tomo e" (愛しき悪友へ, To My Beloved Companion).
The group had a concert tour starting on August 11, 2007, ending September 1, 2007, located in six different stadiums.
