GIRLKIND XJR

GIRLKIND XJR — the name alone brings back a rush of memories for every K-pop fan who followed the underground scene between 2018 and 2022. This K-pop sub-unit was carved out from the larger girl group GIRLKIND (걸카인드), and it became one of the most talked-about Korean female duo acts of its era. Made up of powerhouse performers Xeheun and JK (Jikang), the unit blended sharp hip-hop flows with polished lead vocals to create something that felt genuinely different from the typical idol group formula.

Whether you’re a long-time member of the FANFORCE fandom or you’re discovering GIRLKIND XJR for the first time in 2026, this guide covers everything — from band information and member bios, to their full discography, memorable live performances, and the solo paths each artist carved after the group’s disbandment. Think of this as your one-stop destination for the most complete GIRLKIND XJR member profiles you’ll find anywhere.

Let’s dive in.

The GIRLKIND XJR Member Profiles

Member Overview Table

🎤 XEHEUN (세흔) — Detailed Profile

Xeheun — now also known by her newer stage name Kanni — was the heartbeat of GIRLKIND XJR. As the leader and lead vocalist, she brought emotional depth and star quality every time she stepped on stage. Here’s everything you need to know about her:

XEHEUN

She was an actual orchestra violinist. Before the K-pop world called her name, Xeheun spent time playing the violin in an orchestra — proving she’s been a multi-talented performer from the very beginning.

She has 12 years of dance experience. That’s not a typo. She’s trained in street dance, hip-hop, and ballet, making her one of the most versatile dancers to come out of the mid-sized K-pop agency scene.

She competed on Produce 101. Before GIRLKIND even existed, Xeheun represented Nextlevel Entertainment on the iconic survival show and was eliminated in Episode 5.

She refused to remove her signature mole. Xeheun has a mole above her lip that her company wanted her to remove. She said no — and honestly, fans love her for it.

Her most attractive point? Her own lips. When asked what she thinks is her best feature, Xeheun doesn’t hesitate: it’s her lips.

She has a very strange and very impressive party trick. She can move her ears independently — and she can also copy the echoing sound effect you get in karaoke rooms. It’s a whole vibe.

She appeared in Bolbbalgan4’s Travel music video. Long before the XJR debut, Xeheun popped up in the MV for this beloved Bol4 track.

She went to school with some major K-pop names. NCT’s Mark, GUGUDAN’s Mina, and OH MY GIRL’s Arin were all her classmates. The K-pop pipeline was real.

She and Weki Meki’s Doyeon are close friends. The two have maintained their friendship long after their days as trainees together.

She fully rebranded in 2023. After GIRLKIND disbanded, Xeheun signed with Space Sound and adopted the stage name Kanni, releasing her comeback single “Aprillia” in April 2023 — her first release in five years. She’s also been spotted as a background dancer for GOT7’s Yugyeom on his Trusty tour.

🎤 JK (지강) — Detailed Profile

JK, born Kim Ji-kang, was the rap engine of GIRLKIND XJR. As the group’s main rapper and lead dancer, she brought energy, precision, and a distinct personality that made her incredibly memorable. Here’s the full lowdown:

JK

She is the cleanest member — no contest. JK has a reputation for being obsessively neat. She can walk into any dressing room and immediately feel the urge to organize everything in sight.

Her eyeliner has to be perfectly symmetrical — or else. She is incredibly meticulous about her makeup. If her eyeliner isn’t perfectly even on both eyes, she genuinely will not leave the room until it’s fixed.

She literally learned martial arts because of her dad. JK’s father was a Taekwondo instructor, which is probably why she picked up the sport and became seriously skilled at it — especially her kicks.

She appeared in Bolbbalgan4’s Travel music video. Just like Xeheun, JK also appeared in the Bol4 MV, showing off her dance skills before XJR was even a thing.

She made her solo debut with “Split.” Her solo track, released on March 21, 2019, showed a grittier, more personal side of her artistry.

She’s the shortest member of GIRLKIND. Standing at 161 cm, JK is technically the shortest — but her stage presence makes you completely forget about that.

She’s a Pisces with Taekwondo energy. The combo of creative sensitivity and physical discipline makes her one of the most interesting personalities in K-pop.

She’s known for being the most organized person backstage. If the dressing room is messy when JK walks in, it won’t be by the time she leaves. This is just who she is.

Her rapping style stood out in a crowded market. During GIRLKIND’s active years, JK’s aggressive-yet-melodic rap delivery was consistently called out by fans and critics as a standout quality.

She contributed to the composition and choreography of XJR’s music. JK wasn’t just performing the songs — she was part of creating them, helping arrange choreography alongside Xeheun for several releases.

Achievements

GIRLKIND XJR may have been a sub-unit, but their accomplishments made a real mark on the K-pop underground and beyond. Here are some of their biggest highlights:

• 🏆 Historic International Performance: As part of the parent group GIRLKIND, Xeheun and JK were part of the team that performed at the 2018 Changwon K-Pop World Festival in Bahrain — making them part of the first-ever K-pop girl group to perform in that country.
• 🏆 Successful Makestar Campaign: Before even debuting as XJR, the duo generated huge fan excitement through their Makestar crowdfunding campaign, which hit its goal and proved there was a real appetite for this sub-unit.
• 🏆 Chart Entry with “Good Vibes Only”: The parent group’s 2021 single entered the Melon and Bugs! Top 100 chart within 24 hours, peaking at #39 — a strong showing for an independent label group.
• 🏆 KBS Music Bank Performance: After releasing the XJR debut album Life is Diamond, the duo performed and promoted the title track “Money Talk” on KBS Music Bank, one of Korea’s most prestigious music broadcast shows.
• 🏆 GIRLKIND Tokyo Live 2022: The full group, including both XJR members, performed a Japan concert series at Showbox in Shin-Okubo, Tokyo, running from April 16 to May 7, 2022 — their final major live run.
• 🏆 Songwriting Credits: Both Xeheun and JK participated in writing and composing music throughout their career — from the XJR title track “Money Talk” to GIRLKIND’s single “Future” — showing they were artists in the fullest sense, not just performers.
• 🏆 Post-Disbandment Relevance: Even after GIRLKIND ended, Xeheun (as Kanni) remained active in the industry, working with Space Sound and even joining GOT7’s Yugyeom as a background dancer on his 2025 Trusty world tour — keeping the GIRLKIND name alive among fans.

Final Thoughts

GIRLKIND XJR left behind a legacy that goes way beyond their short active run. Xeheun and JK were a rare pair — two artists who genuinely shaped their sound, wrote their lyrics, built their choreography, and still found time to connect with their fans on a deeply personal level. Their debut mini album Life is Diamond lives on as a cult classic among fans of independent K-pop, and their performances continue to circulate on social media years after the group came to an end.

Whether you’ve been a FANFORCE member since day one or you’re just now falling in love with these two, one thing is clear: their story didn’t end in August 2022. It just changed shape.

Keep following Kanni’s solo journey, keep supporting JK wherever she shows up next, and keep celebrating the music that GIRLKIND XJR gave the world.
