Pristin

Pre-debut

The members Nayoung, Roa, Yuha, Eunwoo, Rena, Kyulkyung and Xiyeon competed together on Mnet's survival television show Produce 101, which aired from January 22 to April 1, 2016. While five of the members were eliminated, Nayoung and Kyulkyung became part of the final line-up for the project girl group I.O.I, which made its debut on May 4 with the single "Dream Girls".

Pledis Girlz

The group was officially announced as Pledis Girlz by Pledis Entertainment on March 23, 2016. On the same day, Eunwoo was featured on the song "Sickness" by Seventeen's Vernon as part of the soundtrack for the webtoon Love Revolution. Pledis Girlz held concerts from May 14 to September 10, 2016, in which the members performed weekly, with the exception of Nayoung and Kyulkyung, who only performed certain concerts due to having been promoting with I.O.I at the time.

On June 27, they released the promotional single "We", which was written by Roa, Eunwoo, Sungyeon and Xiyeon. The music video for the song was used to introduce the members' profiles.

They held their last concert as Pledis Girlz, entitled Bye & Hi, on January 6, 2017, and then renamed to Pristin, a portmanteau of the words "prismatic" (bright and clear) and "elastin" (flawless strength).

2017-2018: Debut, moderate success and Pristin V debut

On March 2, 2017, Pledis Entertainment announced the group's debut through a teaser image. On March 21, Pristin debuted and released their first mini album Hi! Pristin, accompanied by the title track "Wee Woo". They became the first rookie girl group to perform their debut song on a live broadcast during Mnet Present. Pristin was also part of the line-up for the KCON festival held in Japan on May 19. On the same day, a remixed version of "Black Widow" was released as the album's second and final single, which was performed on a few music shows in order to conclude Hi Pristin's promotions.

On June 3, they performed at the 2017 Dream Concert at the Seoul World Cup Stadium. Their second mini album Schxxl Out was released on August 23, along with the single "We Like".

On October 12, it was announced that the youngest member Kyla would take a break from the group's activities due to health issues. She returned temporarily to the United States to focus on her recovery.

On May 8, 2018, it was announced that Pristin would be debuting a sub-unit called Pristin V, consisting of members Nayoung, Roa, Eunwoo, Rena and Kyulkyung. Pristin V made their debut on May 28, 2018 with single album Like A V.

2019: Disbandment

Following the debut of sub-unit Pristin V, Pristin remained inactive as a full group. By May 2019, nearly two years had passed since the release of their second EP, Schxxl Out, while their only release during 2018 had been Pristin V's single album Like a V. During the inactivity, fans repeatedly requested information from Pledis Entertainment about the group's future activities.

On May 24, Pledis announced that Pristin had disbanded following lengthy discussions with the members. The exclusive contracts of Nayoung, Roa, Yuha, Eunwoo, Rena, Xiyeon and Kyla ended that day, while Kyulkyung, Yehana and Sungyeon remained with the agency. Pledis stated that it would support the three remaining members in pursuing individual activities.

On November 3, former members Roa, Yuha, Eunwoo and Rena, using the names Minkyeung, Gyeongwon, Eunwoo and Yaebin, respectively, re-debuted as members of Hinapia alongside Bada under OSR Entertainment. The group debuted with the single album New Start. Despite prospects of a second release, Hinapia disbanded on August 21, 2020.
