Who Is Acid Angel from Asia?
Acid Angel from Asia is the first sub-unit of tripleS, a 24-member South Korean girl group created by Modhaus under the leadership of CEO Jaden Jeong. Jaden Jeong is a well-known producer who previously worked with LOONA, OnlyOneOf, and collaborated with JYP Entertainment, Woollim Entertainment, Sony Music Korea, and Blockberry Creative.
AAA was formed through a fan-voting system called “First Gravity,” where fans determined which members would comprise the group’s inaugural sub-unit. The four members-Kim Yooyeon, Kim Nakyoung, Gong Yubin, and Jeong Hyerin-were officially announced as the lineup on September 25, 2022.
The group made their recording debut on October 28, 2022, with the extended play Access, featuring the lead single “Generation.” While AAA as a standalone sub-unit is no longer actively promoting, its members remain integral to tripleS and have participated in numerous other sub-units including Acid Eyes, EVOLution, LOVElution, Visionary Vision, and more.
Group History
Formation and Pre-Debut
The story of Acid Angel from Asia begins with the broader narrative of tripleS. On February 18, 2022, Modhaus announced the launch of the world’s first “fan-participating girl group,” where fans would play an active role in determining the group’s sub-units through a voting system called “Gravity.”
The members of AAA were gradually revealed as part of tripleS’s S-number system (each member assigned a sequential number based on their reveal). Jeong Hyerin was the second member revealed (S2) on May 17, 2022. Kim Yooyeon was revealed as S5, Kim Nakyoung as S7, and Gong Yubin as S8 on September 9, 2022.
The “First Gravity” fan vote determined the composition of tripleS’s first sub-unit. Kim Nakyoung was selected as the first member on September 22, Jeong Hyerin as the second on September 23, Gong Yubin as the third on September 24, and Kim Yooyeon as the final member on September 25. The quartet was officially named Acid Angel from Asia.
Official Debut
Acid Angel from Asia officially debuted on October 28, 2022, with the release of their first EP, Acid Angel from Asia <ACCESS>. The mini-album featured six tracks, with “Generation” serving as the title track. The day following their debut, the group appeared on NAVER TV’s web variety show #NEXTREND to promote their release.
The music video for “Generation” showcased the group’s fresh, energetic concept and quickly garnered attention for its polished production and catchy hook. The EP also included b-side tracks such as “Rolex,” which further demonstrated the group’s musical versatility.
Breakthrough and Critical Reception
While AAA did not achieve the commercial scale of some larger K-pop groups, their debut was significant for establishing tripleS’s experimental model. The group’s music received positive reviews for its quality production and the members’ performance capabilities.
In December 2022, the group appeared on 1theK’s dance program COUNTDANCE, where they performed choreography from other prominent girl groups including aespa, ITZY, and (G)I-DLE, demonstrating their dance versatility.
Acid Eyes and Beyond
Following their promotional period, AAA as a standalone sub-unit entered a hiatus. However, in July 2023, the members of AAA combined with members of another tripleS sub-unit, +(KR)ystal Eyes, to form a new project group called Acid Eyes. This collaboration released the single “Cherry Gene,” further expanding the AAA members’ discography within the tripleS ecosystem.
In 2026, the individual members of Acid Angel from Asia remain active within tripleS and its various sub-units, contributing to the group’s ongoing evolution.
