The group is composed of nine members: Nayeon, Jeongyeon, Momo, Sana, Jihyo, Mina, Dahyun, Chaeyoung, and Tzuyu. The group debuted on October 20, 2015 with the extended play The Story Begins.
Fun fact:
The show began on May 5th and ended with Nayeon, Jeongyeon, Sana, Jihyo, Mina, Dahyun, and Chaeyoung as the seven Twice members but JYP then announced that he would be increasing the size of the group from 7 members to 9 by adding Tzuyu, who was the "audience's pick" since she was the most popular contestant by the show's end, and Momo, who was added by JYP himself since he felt the group needed someone with Momo's performance abilities.
