UNCHILD 'MEMBERS' (DEBUT)

Who Are UNCHILD?

UNCHILD is shaking up the K-pop scene with a name that literally means rejecting the ordinary. Debuting on April 21, 2026, this six-member girl group under HighUp Entertainment brings a punky, garage-inspired sound that breaks away from traditional pop formulas.

Meet the Leader: Heekie

Profile and Position

Byun Seo-young, professionally known as Heekie, holds the position of leader and main rapper in the unchild kpop group. Born on March 17, 2007, in Namsan-dong, Daegu, South Korea, the 19-year-old Pisces brings an ENFJ personality type to her leadership role. Her stage name has spawned affectionate nicknames among fans, including HeekieHeekie, Byunsyung, and Teacher Byun.

As one of the core unchild members, Heekie represents the color blue and uses the spades emoji (♠️) as her personal symbol. Her keyword "Ready. Set. Burn." and personal motto "Read the rules. Skip the boring parts." reflect the rebellious spirit that defines her approach to both leadership and artistry. The teaser content for her debut showcase featured Heekie standing in the middle of a road, waving a flag while singing the chorus of their debut track, an image that captured her bold, unapologetic presence.

Training Background

Heekie carries the distinction of having the longest training period among all unchild kpop members, spanning eight years before the group's 2026 debut. Her path through the K-pop training system reflects persistence and adaptability across multiple major agencies.

Her journey began as a student at Def Dance Skool (also referred to as Def Dance Academy), where her talent attracted attention from multiple entertainment companies. In 2018, YG Entertainment recruited her as a trainee, marking the start of her formal idol preparation. After three years at YG, she moved to Source Music in April 2021, where she trained for two additional years. Finally, HighUp Entertainment accepted her as a trainee in April 2023, three years before the unchild kpop profile would be revealed to the public.

The unchild kpop group officially revealed Heekie as a member on April 8, 2026, just days before their April 21 debut.

Personality and Hobbies

Heekie channels her creative energy into diverse pursuits. Her hobbies include clothes shopping, studying fashion trends, making zentangles (intricate pattern drawings), dancing, rapping, and song composition. These interests align naturally with her role as main rapper and reveal a member deeply invested in both visual and musical artistry.

She shares her home with a pet puppy. Her dislikes are specific: ill-mannered people, eggplants, mushrooms, and horror movies. This combination of preferences paints a picture of someone who values respect and has clear boundaries.

Her bucket list demonstrates ambitious goals for the unchild members' future: winning rookie of the year awards, holding a solo concert, organizing fan meetings, embarking on a world tour, participating in university festivals, and attending end-of-the-year awards ceremonies. These aspirations mirror the group's stated determination to shake up the industry as rule-breakers, with Heekie positioned at the forefront of that mission.

The Visual Center: Yeeun

Profile and Position

Park Yeeun serves as the lead vocalist, visual, and center of the unchild kpop group. Born on December 21, 2006, in Munsan-eup, Paju, Gyeonggi-do, South Korea, the 19-year-old Sagittarius stands at 170 cm tall. Her MBTI personality type is ESTP, though it previously registered as ISTP. Fans affectionately call her by the nicknames Yen and Yejun.

As one of the central unchild members, Yeeun represents cyan as her individual color and uses the club emoji (♣️) as her personal symbol. Her keyword "My-Pace Specialist" and personal comment "The finish line? Where I say it is" capture her self-determined approach to career and artistry. HighUp Entertainment officially introduced her as an unchild kpop member on April 7, 2026, through a teaser showing her running through tracks with blazing red hair as she approached a microphone.

Training Background

Yeeun's path to joining the unchild kpop profile began through competitive survival show experience. She participated in Mnet's I-LAND 2: N/a as a WAKEONE trainee from April to May 2024. During the competition, she gained recognition for her strong visuals, earning the nickname "Little Jisoo". She even became one of Han Yujin's favorite contestants on the show. Her journey ended in episode 7, where she ranked 14th overall after elimination. Notably, during her I-LAND 2 run, her profile hashtags included #HongdaeStreetCastingGoddess and #MoonSanHighKARINA, with the motto "Everyone will fall for my charm!".

Subsequently, in January 2025, local media outlet OSEN revealed that Yeeun had joined HighUp Entertainment as a trainee for their upcoming girl group. She attended Munsan High School, where she participated in the school's dance club before her professional training began. Her school nickname was "Karina". Before entering the industry, she appeared in a Korean street interview YouTube channel in Hongdae during August 2023.

Personality and Hobbies

Yeeun channels her creativity into making beaded accessories and playing games. She describes her charm point as her down-to-earth and honest personality combined with an innocent outer appearance. Her love for horror movies stands out among her interests, while hamburgers rank as her favorite food.

Her dislikes are specific: bugs and loneliness. She openly expresses her admiration for THE BOYZ, choosing member Sunwoo as her ideal type because she appreciates people with slight double eyelids and a cute style. Additionally, she follows LE SSERAFIM's Kim Chaewon and Paul Blanco.

Her bucket list reflects ambitious goals shared across unchild kpop members: winning a rookie of the year award and embarking on a world tour. These aspirations align with the group's stated determination to shake up the industry while maintaining their distinctive, rule-breaking identity.

Friendship Ambassador: Tina

Profile and Position

Bian Tianyu, known professionally as Tina, brings Chinese representation to the unchild kpop group as their visual, lead dancer, and sub-vocalist. Born on March 9, 2008, in Beijing, China, the 18-year-old Pisces carries the Korean name Byeon Cheon-eon (변천언) and stands at 164 cm tall. Her MBTI personality type registers as INFP.

Notably, Tina holds the distinction of being the first Chinese artist to debut under HighUp Entertainment.

Tina's path to the unchild kpop profile spanned multiple agencies across three years. She began her training journey at XTS Entertainment in 2023, remaining there through 2025. During this period, she briefly joined Pledis Entertainment in 2024 before departing in 2025. Afterward, she transitioned to HighUp Entertainment sometime in 2025.

Her public recognition came through competitive survival programming. In 2024, while still under the stage name Kittie, she appeared as a contestant on the Thai reality survival program Chuang Asia Thailand. The competition ended with her elimination in the fifth episode, where she ranked 42nd overall.

Personality and Hobbies

Tina describes her personality as resembling a cat's temperament. She likes people but finds approaching them first particularly difficult. This reserved nature contrasts with her creative pursuits, which include listening to jazz and soul music, taking walks at sunset, and making frog sounds.

Her favorite color is blue. Physically, she possesses extreme flexibility, while her eyes serve as her charming point. She created the fandom logo for CHACHA, demonstrating her artistic contributions beyond performance.

Before debut, Tina gave each unchild kpop member personalized gifts. Her bucket list includes cooking with the members, traveling together, and having a girls' night out. She aspires to release an R&B track in the future. When facing struggles, she watches old videos to regain proper headspace. Her personal motto reflects optimism: "Let's live a good and happy life".

Self-Love Queen: Ako

Profile and Position

Sasaki Ako embodies the philosophy of self-love as the unchild kpop group's designated "Self-Love Club President," paired with her personal declaration: "Loving yourself isn't a hobby. It's a full-time job". Born on July 8, 2008, in Fukuoka, Japan, the 17-year-old Cancer brings an ISFJ personality to her role as sub-vocalist. She describes her own character as "quirky, or rather, slightly unusual".

As one of the unchild members, Ako represents magenta as her individual color and uses the ribbon emoji (🎀) as her personal symbol. She holds a significant distinction within the unchild kpop profile: as of 2026, she is the first Japanese artist to debut under High Up Entertainment. Fans call her by affectionate nicknames including Ako Chan (아코짱), Eiko (에이코), and Lee Ako (이아코).

HighUp Entertainment revealed her as an unchild kpop member on April 8, 2026.

Training Background

Ako's journey through the K-pop training system spanned three and a half years across multiple major agencies. Her path began at YX LABELS before moving to Belift Lab, where she trained as part of HYBE Labels Japan's development program. During her time at Belift Lab, she formed friendships with some contestants from the R U Next? survival show.

She joined High Up Entertainment sometime in late 2022 or early 2023, marking the transition that would lead to her groundbreaking position as the company's first Japanese debut artist. Her inspiration to pursue K-pop idol status came at a young age: attending a BTS live performance when she was in fourth grade sparked her dream. Growing up, she consistently sang and danced to Girls' Generation's Japanese songs, with the group serving as a significant influence alongside her parents.

Personality and Hobbies

Ako channels her energy into eating, watching anime, taking walks while listening to music, and making funny faces. She enjoys people who like her, food, indoor sports, and filming TikToks. Conversely, she dislikes high places, bugs, and saying the same thing over and over.

She considers her charming traits to be her smiling face, weird personality, and hard work. Her bucket list reflects both personal and group-oriented aspirations: baking desserts with the unchild kpop members, taking a trip to Fukuoka with the group, and doing a mini sports test.

Main Vocalist: Evon

Profile and Position

Lee Ji-min carries the stage name Evon, pronounced as "Yvonne," serving as main vocalist among the unchild kpop members. Born on July 11, 2008, in Gwanak-gu, Seoul, South Korea, the 17-year-old Cancer possesses an ISFJ personality type. Her Chinese zodiac sign is Rat.

Within the unchild kpop profile, Evon represents purple as her individual color and uses the purple heart emoji (💜) as her personal symbol. Her assigned keyword "Effortlessly Weird" pairs with the personal comment "I don't know why you're surprised", reflecting her unpredictable nature. Fans know her by the affectionate nickname Voni (보니).

HighUp Entertainment revealed her as an unchild kpop member on April 8, 2026. Notably, Evon identifies herself as the only calm member within the group's energetic dynamic. Her representative animal is a flamingo, and she claims chapagetti as her signature dish. When asked to define herself in one word, she chose "Film".

Training Background

Evon's journey toward joining the unchild kpop group began at Def Dance School (also referenced as Def Music Academy), where she received foundational training. Interestingly, she and leader Heekie first met as fellow students at this institution, establishing a connection that would later reunite them in UNCHILD.

HighUp Entertainment accepted her as a trainee in October 2023. She completed a training period of two-and-a-half years before debut, a relatively moderate duration compared to some industry standards. Her education included Seoul Guam Elementary School, Guahm Middle School, and Guahm High School, though she dropped out of high school to pursue her idol career.

Her aspirations for becoming a K-Pop idol date back to kindergarten, demonstrating early commitment to this career path. Among her professional goals, performing on a big stage like Coachella stands as one of her key aspirations.

Personality and Hobbies

Offstage, Evon exhibits a very shy personality, contrasting with her confident performance presence. Her hobbies include sleeping, singing, and laughing a lot, activities that reflect her lighthearted approach to downtime. She looks to BLACKPINK's Rosé as her role model.

Her favorite foods encompass salt bread, honey rice cakes, and meat. Conversely, she maintains strong aversions to green onions, cilantro, bell peppers, celery, and ginger.

Her bucket list reveals balanced priorities: having lots of activities while being happy and healthy, and winning the rookie of the year award. This combination reflects both personal wellness values and professional ambition shared across unchild kpop members.

Evon defines true freedom as taking responsibility for one's choices without being bound to moulds, a philosophy that aligns with the unchild kpop group's core identity of rejecting ordinary standards.

Dance Prodigy Maknae: Haeun

Profile and Position

Na Ha-eun's recognition as a "dance prodigy" preceded her role as the unchild kpop group's main dancer and maknae by over a decade. Born on January 16, 2009, in Namsan-dong, Jung-gu, Daegu, South Korea, the 17-year-old Capricorn earned her title after starring in "Star King" in 2013 at just four years old. Performing alongside HyunA during that appearance earned her the nickname "Baby HyunA".

Within the unchild kpop members lineup, Haeun represents green as her individual color and uses the star emoji (⭐) as her personal symbol. Her assigned keyword "Zero Hesitation Mode" pairs with the declaration "Doesn't overthink. Over-does", reflecting an approach shaped by years of solo performance before joining a team. Fans call her by affectionate nicknames including Nyanghani, Puppy-Cat, Golden Retriever, and Baby. Her MBTI personality type is ENFP.

HighUp Entertainment revealed her as the first unchild kpop member on November 27, 2025, through an interview with GQ Korea, marking her as the face introducing the group to the public.

Training Background

Haeun's path to the unchild kpop profile began with early television exposure. At age six, she participated in the fourth season of K-pop Star in 2014, becoming the show's youngest contestant. That same year, she launched the YouTube channel "Awesome Haeun," uploading dance covers and accumulating over 2 million subscribers by 2018. She performed at the Melon Music Awards in 2017, 2018, and 2019, introducing Best Dance nominees through choreographed performances.

In April 2022, SM Entertainment announced signing her to an exclusive contract. After two years at SM, she left the company in August 2024. By September 10, 2024, she joined HighUp Entertainment, completing a three-year training period before debut. Notably, Haeun and leader Heekie took part in creating portions of UNCHILD's debut choreography.

Personality and Hobbies

Haeun described her debut as a long-awaited moment: "I used to dance alone a lot, so I always dreamed of performing with others. Being able to practice and go on stage together as a team feels really special. It's reassuring, almost like having an Avengers team". She acknowledged pressure surrounding her debut but transformed it into motivation to show a stronger side as an idol.

Her hobbies include dancing, eating delicious food, shopping, listening to music, taking back camera selfies, and learning choreography while lying down. She looks to BTS's Jimin and EXO's Kai as role models. Besides performance activities, she created the CHACHA fandom name and describes herself as resembling carbonated drinks due to her refreshing energy. Her bucket list includes having a girls' night out dance party with unchild kpop members, going diving, and meeting fans on the street.

UNCHILD's Multinational Lineup and Diversity

Korean Members

Four of the six unchild kpop members hail from South Korea: leader Heekie, center Yeeun, main vocalist Evon, and maknae Haeun. This Korean majority anchors the group's identity while allowing international representation to complement rather than overwhelm the core lineup. Heekie and Haeun both originate from Namsan-dong, Daegu, establishing a regional connection within the leadership and youngest member dynamic. Yeeun brings representation from Paju, Gyeonggi-do, while Evon represents Seoul's Gwanak-gu district.

Chinese Member Tina

Tina broke ground as the first Chinese artist to debut under High Up Entertainment, bringing Beijing representation to the unchild kpop profile. Her inclusion reflects the agency's strategic expansion beyond purely Korean lineups. By comparison, major agencies like SM Entertainment and JYP Entertainment had incorporated Chinese members decades earlier, making Tina's milestone significant specifically within High Up's trajectory. Her visual and lead dancer positions place her prominently within the group's performance structure.

Japanese Member Ako

Identically, Ako achieved a parallel milestone as the first Japanese artist to debut under High Up Entertainment. Her Fukuoka roots add geographic diversity beyond Tokyo-centric Japanese idol representation. The inclusion of both Chinese and Japanese members positions the unchild kpop group within a broader industry trend toward multinational formations.

Cultural Representation in K-Pop

The unchild members' three-nation composition reflects K-pop's evolution from homogeneous groups to culturally diverse lineups. Super Junior's Chinese member Hangeng, EXO's multiple Chinese members including Lay and Kris, and TWICE's Japanese members (Momo, Sana, Mina) alongside Taiwanese Tzuyu established precedents dating back to the early 2000s. This diversification sparks ongoing debate: some fans argue K-pop's essence lies in its Korean cultural identity, while others view multinational membership as natural evolution for a globally resonant genre. The discussion highlights K-pop's dual nature as both distinctly Korean cultural export and boundary-crossing global phenomenon.

UNCHILD Kpop Members' Unique Concepts and Aesthetics

Rebellious and Bold Style

UNCHILD's visual identity centers on what the agency describes as a "freaky punk" aesthetic that reinterprets classic punk motifs through a Gen Z lens. Rather than following traditional K-pop styling, the unchild kpop members embrace bold neon-colored hair, school uniform hacking, and kitschy accessories including toy guns and game consoles. This maximalist approach transforms familiar school settings into what they call "PUNK SCHOOL," conveying overwhelming liberation and free-spirited energy.

The group's teaser content showcased vivid neon-colored visuals enhanced by pop art-inspired direction, highlighting each member's individuality. Styled in playful yet rebellious fashion, their debut material featured mismatched manicures and punky high school-esque outfits that signal their identity as rule breakers. The tadpole symbol serves as their visual mascot, representing defiance against standardized molds.

Individual Representative Colors and Emojis

Besides visual styling, each member carries an assigned representative color and emoji that fans use for identification. These personal symbols were revealed through the group's official social media channels.

Breaking K-Pop Norms

The term "freaky" sparked initial confusion, but context clarifies its meaning as unconventional rather than provocative. Their Gen Z-driven perspective actively breaks away from convention, positioning the unchild kpop group to deliver fresh impact to the industry through their signature "Freaky" mood representing quirky and unconventional sensibilities.
