is a Japanese girl group, which consists of six members Misako Suzuki, Ringo Koishio, Gumi Nanase, Miyu Mochizuki, Yuzu Amanatsu, and Sunrise Omomoko.

In February of the same year, the two held their first live performance as Band Ja Naimon.

Initially, they asked other musicians to support them on stage with other instruments, but later decided that only the two would perform with both members playing drums and singing.

They released their self-titled debut album on October 3, 2012, under Warner Music Japan's label, unBORDE.

Her graduation concert was held on September 19, 2013, marking the end of the “twin-drum” era.

That same day, Yuzu Amanatsu and Omoko Sunrise (known as Momoko Amaterasu at the time) were announced as the new members.
