tripleS is a multinational South Korean girl group formed by the entertainment company Modhaus in 2022, comprising 24 members from South Korea, Japan, Taiwan, and Thailand.[1][2] Billed as the world's first decentralized K-pop idol group, tripleS operates under a fan-centric model where supporters, known as "WAV," participate in decision-making through voting on subunit lineups, track selections, and activities via digital platforms and NFTs.[3][4][5] This innovative structure allows members to rotate fluidly between the full ensemble, various subunits, and solo projects, embodying the group's cosmic theme of infinite possibilities.[6]The group initiated its activities with the debut of its first subunit, Acid Angel from Asia (comprising members Jeong Hye-rin, Kim Yoo-yeon, Kim Na-kyoung, and Gong Yu-bin), on October 28, 2022, releasing the EP Access.[7][8] tripleS then launched as a 10-member unit on February 13, 2023, with the mini-album ASSEMBLE and the lead single "Rising," marking the official group debut under producer Jaden Jeong's vision.[9][10] By May 8, 2024, all 24 members— including later additions like Kaede, Kotone, and Xinyu—united for the full-group debut album ASSEMBLE24, which featured the title track "Girls Never Die" and showcased the decentralized format through multiple subunit performances.[11] In 2025, the group released their second full-length album ASSEMBLE25 in May and announced a 24-member mega-unit comeback with the album Beyond Beauty in November.[12]Since its inception, tripleS has released several subunit albums and singles, such as Acid Angel from Asia's Access (2022) and LOVElution's Girls' Capitalism (2023), emphasizing thematic narratives around empowerment and evolution.[5] The group's approach has garnered attention for challenging traditional K-pop hierarchies, with no fixed leader and fan input driving creative directions, leading to global tours, brand collaborations, and a growing international fanbase as of November 2025.[13]
Background
Name
The name "tripleS" was officially announced by MODHAUS, the group's management company led by CEO Jaden Jeong, on April 4, 2022, via a teaser video titled "tripleS 트리플에스 : thesis" released on their social media platforms and YouTube channel.[14]The name serves as an acronym for "Social Sonyo Seoul," where "Social" emphasizes the group's interactive and fan-participatory approach, "Sonyo" translates to "girls" or "young women" in Korean, and "Seoul" denotes their base of operations, collectively portraying the members as vibrant, socially connected idols from the South Korean capital.[14] This etymology also symbolizes the unification of individual members—represented by lowercase "s"—into a cohesive whole, akin to forming a capital "S," which aligns with the group's decentralized structure enabling fan-driven decisions on activities.[14]Stylistically, the name is primarily rendered as "tripleS" in official branding, with "SSS" as a common shorthand abbreviation; however, variations such as the lowercase "triples" appear in certain promotional materials, subunit contexts, and fan communications to evoke a more casual, approachable tone.[14]
Concept
TripleS operates as the world's first decentralized K-pop idol group, a model pioneered by its agency MODHAUS to integrate fan participation directly into the group's structure and activities.[15][1] In this system, the traditional fixed lineup of K-pop groups is replaced by a fluid, fan-influenced framework where supporters actively shape the project's direction through voting mechanisms. This approach leverages Web3 technologies to empower fans, known as "WAV," to decide on key elements such as subunit formations and creative concepts, fostering a sense of co-ownership in the group's evolution.[4][2]Central to the decentralized model is the Cosmo app, a blockchain-based platform that enables fans to cast votes on subunit compositions and influence artistic decisions, including music releases and content production. Developed by MODHAUS and powered by the Abstract blockchain, the app facilitates immersive fan engagement, allowing users to participate in real-time polls that determine which members collaborate on projects.[16][4] This voting system extends beyond mere suggestion, directly impacting the group's output and marking a shift from agency-led control to a collaborative, community-driven process in the K-pop industry.[17]The group's thematic foundation lies in the "Cosmo" universe, a fictional lore that interconnects the 24 members across diverse realms and dimensions, portraying them as entities navigating cosmic narratives. This universe serves as the narrative backbone, with teasers and multimedia content weaving stories of exploration and unity among the members' personas, enhancing the metaverse immersion.[1] The lore emphasizes boundless possibilities, aligning with the group's ethos of rotation and adaptability.[15]Announced by MODHAUS in February 2022, TripleS was envisioned to debut its full roster of 24 members through rotating subunits rather than a static ensemble, allowing for dynamic configurations based on fan input to maximize versatility and fan connection.[18][19] This structure aims to redefine idol group dynamics by treating the collective as an ever-evolving entity within the metaverse, where no single lineup defines the whole.[2]
History
2022–2023: Formation, pre-debut, and initial subunit debuts
MODHAUS, a South Korean entertainment agency, was founded on November 30, 2021, by Jaden Jeong, a music producer with prior experience at JYP Entertainment, Woollim Entertainment, Sony Music Korea, and Blockberry Creative as creative director and A&R. On February 18, 2022, MODHAUS announced the launch of TripleS, described as the world's first "fan-participating girl group" intended to eventually consist of 24 members selected through a decentralized, blockchain-based system involving fan votes via NFTs. This innovative concept allowed fans to influence group activities, including subunit formations, marking a shift toward Web3 integration in K-pop.Member reveals for TripleS began on May 1, 2022, with Yoon Seo-yeon introduced as the first member (S1) through a teaser video showcasing her move into the group's dormitory, known as the HAUS. Subsequent reveals occurred roughly every two weeks, introducing Jeong Hye-rin (S2) on May 17, Lee Ji-woo (S3) on June 1, Kim Chae-yeon (S4) on June 22, Kim Yoo-yeon (S5) on July 11, Kim Soo-min (S6) on August 8, Kim Na-kyoung (S7) on August 22, Gong Yu-bin (S8) on September 9, Kaede (S9) on November 9, and Seo Da-hyun (S10) on December 9, completing the initial lineup of 10 members for the group's debut.[20][21] These pre-debut activities built anticipation through teaser content on social media and the official HAUS app, where fans could engage early with the project's participatory elements. In 2023, additional members were revealed: Kotone (S11) on January 2, Kwak Yeon-ji (S14) on February 7, Nien (S12) on April 17, Park So-hyun (S15) on April 24, Xinyu (S13) on July 4, and Mayu (S16) on July 19, enabling further subunit formations.[14]The first subunit, Acid Angel from Asia (AAA), consisting of members Kim Yoo-yeon, Kim Na-kyoung, Gong Yu-bin, and Jeong Hye-rin, debuted on October 28, 2022, with the mini-album ACCESS, led by the single "Generation." This release introduced TripleS's musical style blending electronic pop and experimental sounds, while emphasizing the group's multiverse narrative. On February 13, 2023, TripleS made its official debut as a 10-member unit with the mini-album ASSEMBLE, featuring the title track "Rising" and including contributions from the revealed members up to that point. The debut showcase at Blue Square Mastercard Hall in Seoul highlighted synchronized choreography and fan interaction mechanics, solidifying the group's unique approach.In the months following, additional subunits debuted to expand TripleS's activities, all formed through fan voting on the official platform to select lineups from the existing members. The second subunit, +(KR)ystal Eyes (KRE), comprising Yoon Seo-yeon, Kim Soo-min, Kim Chae-yeon, and Lee Ji-woo, released its debut mini-album AESTHETIC on May 4, 2023, with the lead single "Do not touch." This was followed by Acid Eyes, a combination unit of AAA and KRE members, which debuted on July 6, 2023, with the digital single "Cherry Gene," focusing on a bolder, electronic aesthetic. Later in 2023, LOVElution, featuring Lee Ji-woo, Kim Chae-yeon, Kim Yoo-yeon, Kim Na-kyoung, and Kotone, debuted on August 17, 2023, with the mini-album ↀ (Muhan) and title track "Girls' Capitalism," emphasizing themes of empowerment and consumerism. These early promotions introduced the fan voting system more prominently, allowing supporters to propose and vote on future subunit concepts, fostering community involvement in the group's evolution.
2024: Full group debut, additional subunits, and early tours
In early 2024, following the addition of four members in December 2023, tripleS revealed its final four members from April 1 to April 4, completing the 24-member lineup with Kim Chae-won (S21), Sullin (S22), Seo-ah (S23), and Ji-yeon (S24).This brought the total to 24 active members, enabling the group's first full-team activities. On May 8, 2024, tripleS debuted as the complete OT24 with their first studio album, ASSEMBLE24, a 10-track release led by the title track "Girls Never Die."The album emphasized themes of resilience and unity, with contributions from all members, and was launched alongside a showcase event that highlighted the group's synchronized performance style.ASSEMBLE24 achieved notable chart success, entering the top 10 on South Korean platforms and marking tripleS's first entry on Billboard's World Albums chart.Building on the subunits debuted in 2022–2023, such as Acid Angel from Asia and EVOLution, tripleS introduced additional units in 2024 to explore diverse musical dimensions.The seventh subunit, Aria—a ballad-oriented unit consisting of Seo Da-hyun, Lee Ji-woo, Kim Chae-yeon, Nien, and Kaede—debuted on January 15, 2024, with the single album Structure of Sadness and its poignant lead single "Door.""Door" focused on themes of emotional vulnerability and closure, receiving praise for its vocal harmonies and minimalistic production.In June, the eighth subunit Glow, formed exclusively from the newest members (Kim Chae-won, Sullin, Seo-ah, and Ji-yeon), debuted on June 21, 2024, with the digital single "Inner Dance."This release blended upbeat pop with introspective lyrics about self-discovery, serving as an introduction for the final additions to the group.October brought the debut of the ninth subunit, Visionary Vision, a 12-member dance-focused unit curated through fan voting on the GRAVITY platform, including pre-selected members like Yu-bin and Lynn alongside voted-in talents such as Hye-rin, Na-kyoung, and Xinyu.They released their full-length debut album Performante on October 23, 2024, led by the high-energy track "Hit the Floor," which addressed societal pressures and featured intricate choreography.Performante sold over 80,000 copies in its first week, setting a record for subunit album sales among girl groups.In late 2024, tripleS formed its tenth subunit, the Japanese-market oriented ∞! (pronounced Hatchi), an eight-member unit including Japanese members Kotone and Mayu alongside Korean talents like Ji-woo and Yoo-yeon.Announced on September 14, Hatchi debuted on November 20, 2024, with the single "Untitled," a dreamy track aimed at bridging the group's concepts with J-pop influences.Early live activities in 2024 included the "Authentic in Seoul" concerts on February 3 and 4 at Yes24 Live Hall, where 20 members performed hits from prior subunits and previewed full-group material.These shows, part of the ongoing Authentic tour series initiated in 2023, drew over 5,000 fans and underscored tripleS's growing stage presence before the OT24 era.
2025–present: ASSEMBLE25, world tour, msnz formation, and mega-unit comeback
In early 2025, tripleS launched their first world tour titled "tripleS Come True," commencing on February 1 in Orlando, Florida, with subsequent North American stops including Brooklyn, New York, and extending to Asia and the Middle East, such as a performance at the Dream Concert in Abu Dhabi on November 22. The tour highlighted the group's expanding global reach, featuring full-group performances alongside subunit showcases to support their evolving universe concept.On May 12, tripleS released their second full-length album, ASSEMBLE25, following their 2024 debut album, with the lead single "Are You Alive" emphasizing themes of awakening and unity among the 24 members. The album marked a significant milestone in their discography, incorporating fan-voted elements from prior Grand Gravity events and achieving strong initial sales. To complement the tour, the eight-member subunit Alphie—consisting of YooYeon, Nien, JiYeon, Kotone, ShiOn, Lynn, ChaeWon, and HaYeon—was formed in early 2025 specifically for promotional support, releasing the English track "Lit Pop" ahead of the "Alpha Percent" tour leg.Throughout the year, tripleS issued several additional releases, including the collaborative single "Pink Power" with ZANMANG LOOPY on July 17, the Japanese version of "Girls Never Die" on April 12, and the OST track "PainDrop" performed by members SeoYeon, JiWoo, YuBin, and SoHyun for the drama Friendly Rivalry on March 4. In October, the subunit Hatchi made a comeback with their first Japanese EP, SecretHimitsuBimil, on October 1, blending K-pop and J-pop elements to target international audiences. In late 2025, tripleS introduced the msnz subunit cluster, comprising four six-member units—Moon, Sun, Neptune, and Zenith—announced as a new "mirrored DIMENSION" to further expand their universe narrative. This formation culminated in the announcement of a 24-member mega-unit comeback titled Beyond Beauty on November 1, set for release on November 24, uniting all members for a high-impact project focused on collective beauty and synergy.

Subunits
TripleS's subunit system is a core element of its innovative structure, allowing the 24 members to form dynamic lineups that explore various "dimensions" within the group's universe narrative, where each member possesses a unique "S" ability. Subunits are typically created through fan-driven "Grand Gravity" voting events, enabling supporters to select members, themes, and even song concepts, fostering direct engagement and diversity in musical and visual expressions. This approach has resulted in a range of subunits with distinct identities, from intimate ballad groups to expansive performance ensembles, all contributing to the full group's evolving lore without fixed permanent lineups.[13]The inaugural pre-debut subunit, Acid Angel from Asia, comprises four members: Jeong Hye-rin, Kim Yoo-yeon, Kim Na-kyoung, and Gong Yu-bin. Its concept revolves around an angelic, harmonious presence symbolizing unity and ethereal grace across Asian influences, marking the first exploration of the group's multi-dimensional world.[22]+(KR)ystal Eyes, formed via the initial Grand Gravity, features four members: Yoon Seo-yeon, Lee Ji-woo, Kim Chae-yeon, and Kim Soo-min. The unit's theme draws on crystalline clarity and Korean-inspired aesthetics, emphasizing sparkling visuals and synchronized, jewel-like performances that highlight the members' radiant "S" powers.[23]LOVElution, selected through the second Grand Gravity, includes eight members: Yoon Seo-yeon, Jeong Hye-rin, Gong Yu-bin, Kaede, Seo Da-hyun, Nien, Park So-hyun, and Xinyu. This subunit embodies a theme of romantic evolution and emotional liberation, blending pop elements with heartfelt narratives to represent love as a transformative dimension.[6]EVOLution, also from the second Grand Gravity, consists of eight members: Kim Yoo-yeon, Kim Soo-min, Kim Na-kyoung, Kim Chae-yeon, Lee Ji-woo, Kotone, Kwak Yeon-ji, and Mayu. Its concept centers on growth and resilience, likened to diamonds forming under pressure, focusing on powerful, evolving dynamics and inner strength.[24]Aria, a fan-voted ballad-oriented subunit, features five members: Seo Da-hyun, Nien, Kim Chae-yeon, Lee Ji-woo, and Kaede. The theme evokes an ethereal fantasy realm of sorrow and serenity, prioritizing vocal depth and intricate harmonies to convey emotional landscapes.[14]tripleS Glow, a non-voted introductory subunit for the final members, includes four members: Lee Chae-won, Sullin, Seo Ah, and Kim Ji-yeon. Its concept emphasizes luminous introduction and fresh energy, serving as a bridge to integrate newer members into the group's glowing, optimistic dimension.[25]Visionary Vision, a large-scale dance subunit formed through fan input, comprises 12 members: Jeong Hye-rin, Kim Yoo-yeon, Kim Na-kyoung, Gong Yu-bin, Kaede, Kotone, Kwak Yeon-ji, Nien, Park So-hyun, Xinyu, Lynn, and Kim Ji-yeon. The unit's theme pushes boundaries of choreography and stage innovation, aiming to visualize futuristic visions through high-energy, synchronized routines.[26]Hatchi (∞!), an 8-member Japanese-focused subunit, features Mayu, Shin Shi-on, Kim Yoo-yeon, Kotone, Lee Ji-woo, Kim Soo-min, Kim Chae-yeon, and Lee Chae-won. Its concept explores infinite possibilities and secretive bonds, with a bilingual emphasis on cross-cultural appeal and mysterious, unfolding narratives.[14]Alphie, an 8-member special unit created for the 2025 world tour, consists of Kim Yoo-yeon, Kotone, Nien, Lynn, Jeong Ha-yeon, Shin Shi-on, Lee Chae-won, and Kim Ji-yeon. The theme highlights alpha-level energy and global connectivity, designed to showcase versatile performances tailored for international audiences.[27]In 2025, the msnz project introduced four interconnected clusters—Moon, Sun, Neptune, and Zenith—each with six members, formed via a dedicated Grand Gravity event to represent mirrored dimensions in the tripleS universe. Moon (leader: Sullin; members: Kim Ji-yeon, Park So-hyun, Kaede, Shin Shi-on, Lynn) embodies nocturnal mystery and introspective calm. Sun (leader: Xinyu; members: Kim Yoo-yeon, Mayu, Lee Chae-won, Kim Chae-yeon, Jeong Hye-rin) captures solar vitality and bold radiance. Neptune (leader: Yoon Seo-yeon; members: Kim Na-kyoung, Seo Da-hyun, Kotone, Nien, Seo Ah) evokes oceanic depth and fluid adaptability. Zenith (leader: Jeong Ha-yeon; members: Gong Yu-bin, Lee Ji-woo, Kim Soo-min, Kwak Yeon-ji, Kim Joo-bin) symbolizes peak achievement and aspirational heights. These clusters collectively form a mega-unit comeback, emphasizing balanced, cosmic synergy.[28][29]
Membership timeline
The membership of TripleS was built gradually through sequential reveals, starting with an initial core group and expanding to incorporate diverse nationalities, culminating in a stable 24-member lineup by mid-2024 with no subsequent departures, hiatuses, or additions reported as of November 2025. This approach aligns with the group's metaverse-inspired concept, where members are introduced as "planets" in a cosmic narrative. The composition features 18 South Korean members, 4 Japanese (Kaede, Kotone, Lynn, Mayu), 1 Chinese (Xinyu), and 1 Taiwanese (Nien), promoting a multinational dynamic without any lineup changes post-2024.[14][7]The table below outlines the chronological expansion of the group's membership:

Artistry
Musical style
TripleS's music is characterized by a fusion of hyperpop, electronic dance music (EDM), and synth-pop, often incorporating experimental elements that blend maximalist production with glitchy, futuristic soundscapes. This style draws from the group's decentralized structure, allowing for dynamic sonic explorations across full-group releases and subunits, where bold synthesizers, layered vocals, and pulsating beats create an energetic, immersive listening experience. For instance, tracks like those on ASSEMBLE24 feature hyperpop influences through distorted electronic drops and playful vocal manipulations, evoking a Y2K-inspired nostalgia while pushing K-pop boundaries with innovative sound design.[30][31][32]Subunit outputs further diversify the group's palette, with variations tailored to thematic dimensions. LOVElution features upbeat dance-pop with catchy melodies that emphasize youthful energy, as heard in their debut mini-album MUHAN.[33] These subunit styles highlight TripleS's versatility, integrating pop hooks with genre-bending electronics to maintain cohesion within the broader discography.[34]The group's influences stem from K-pop precedents like LOONA's subunit system, which inspired TripleS's modular approach to music creation. Over time, TripleS's sound has evolved from the debut full-group album ASSEMBLE in 2023, which established a trendy, synth-driven foundation, to ASSEMBLE25 in 2025, where fan-input via the COSMO app integrates themes of hope and resilience into the compositions. This progression is evident in ASSEMBLE25's lead single "Wake Up (Are You Alive?)," an alternative dance track that layers harmonious vocals to symbolize awakening amid uncertainty, reflecting fan-voted narratives of perseverance and unity.[35][36][37][38]In 2025, the formation of the msnz subunit introduced further experimental electronic elements, blending synth-pop with atmospheric production in their debut single, expanding the group's sonic dimensions as of November 2025.[39]
Choreography and visuals
TripleS's choreography emphasizes synchronized group formations that leverage the full 24-member lineup to convey scale and unity, often incorporating intricate footwork and wave-like patterns to accentuate the group's dynamic energy.[13] These routines are tailored to highlight subunit-specific elements, allowing individual units to infuse unique flair into the overall performance structure.[40] Under MODHAUS, the group collaborates closely with in-house and affiliated choreographers such as Choi Hyoje and Haley Song, who have directed key works including the choreography for ASSEMBLE24 and subunit releases like AESTHETIC.[40][41]The visual aesthetics of TripleS draw from cosmic and ethereal themes, frequently employing black-and-white palettes in early subunit promotions to evoke a sense of mystery and otherworldliness, as seen in the dual-version packaging for AESTHETIC with its contrasting white and black covers.[42] This motif aligns with the group's overarching "Cosmo" branding, symbolizing interconnected dimensions and fan participation.[1] By 2025, visuals evolved toward vibrant, colorful schemes in ASSEMBLE25 promotions, incorporating bold hues and elemental imagery to represent themes of awakening super abilities and collective assembly.[43] Styling collaborations within MODHAUS prioritize efficiency for large-scale shoots, with dedicated teams handling extended sessions for hair, makeup, and costumes to maintain thematic consistency across performances.[13]
Discography
