Founded November 1999, the group initially consisted of Morning Musume members Kei Yasuda, Sayaka Ichii, and Maki Goto.

Shortly after their formation, the group released their first single, "Chokotto Love," which sold more than 1 million copies.

This sparked yet another formation change, in which Ayaka Kimura (of Coconuts Musume) and 5th generation member Makoto Ogawa were added.

Its new lineup consisted of Cute members Saki Nakajima and Mai Hagiwara; and Erina Mano.
