 (病ンドル) is a 'yami kawaii' (lit. sickly cute) group that debuted on July 20, 2015.

2015

 * In April, 2015, Aina Aoyama graduated from Ayaman JAPAN and set out to create an idol group with the only requirement being that the applicants had to be 'suffering'.
 * Out of over 1400 auditions, Usami Miko, Kisaragi Kira, Kurumi Ruku, Hasumi Ichika, Asahina Maron, and Tsukiyama Suziran where chosen. On July 20, 2015, the group officially debuted as Yandoll.
 * That same day they performed a live show alongside Oyasumi Hologram and LADYBABY.
 * On September 26, 2015, Hasumi Ichika graduated from the group and held her last live. Just four days later, members Asahina Maron (to avoid being hospitalized by her doctor into a mental clinic) and Tsukiyama Suziran also graduated.

2016

 * The group held a second audition, and on January 23, 2016, they revealed three new members, Haruna Nanaha, Takanashi Mayu, and Karei Ruu.
