NA-NA

 was a Kansai-based idol group formed by ESSE Academy on April 10, 2011.

History
The group was formed with seven members, Tamaki, Yuna, Hara Mizuki, Taniguchi Sayane, Rena, Takimoto Yuzuki (alternately spelled Yuduki) and Haruna. However, a girl named Ayaka appears in a November 6, 2011 video. At some point Tamaki, Haruna and Ayaka left, and Kimura Karin joined in February 2012. By the end of March 2012 Rena had left. The five member version of NA-NA, Mizuki, Yuzuki, Sayane, Yuna and Karin, stayed together until sometime in 2013 when Yuna left. Honda Touko eventually joined NA-NA giving the group five members again. Originally performing cover songs, NA-NA progressed to performing an original song titled “Candy☆Machine ni Notte”. In June 2013, they were signed to T-Palette Records along with their “older sister” group, Caramel☆Ribbon. NA-NA played at TOKYO IDOL FESTIVAL 2013. On December 2, 2013 it was announced on the ESSE Academy blog that Yuzuki was leaving to concentrate on her studies. NA-NA had their first “One Man Live” on May 31, 2014 and returned to TOKYO IDOL FESTIVAL in 2014. In early November 2014 Karin announced that she was taking a break from December 2014 to March 2015 to study for high school exams. Karin announced her graduation on July 4, 2015. NA-NA broke up on March 25, 2016.

Touko joined a new group named Colorful Scream in January 2017. NA-NA returned for a one day, two time slot, performance on August 27, 2017. NA-NA decided to stay together performing live for each member’s birthdays instead of breaking up after their August 27, 2017 performances. NA-NA had a fan meet and greet on both November 10 and 20, 2018 before their final performance together on November 25. NA-NA's slogan was “Cute, sweet and cheerful. Like a fairy!”
