SIKKOO Members Profile 2026: Ages, Roles & Facts
SIKKOO (식구) arrived in the Korean hip-hop scene with a name that literally means “family members who share meals.” Signed to AOMG, the co-ed trio debuted on April 29, 2025, with the EP GAN (간). What sets SIKKOO apart is not just their mixed-gender lineup-a rarity in Korean hip-hop-but the fact that the group was built from the ground up by its own leader, Koo Min-jae, before AOMG brought them into its rebranded “AOMG 2.0” era.
SIKKOO occupies a specific lane: “domestic hip-hop” (국산 힙합), a sound that draws from Korean linguistic wit, everyday humor, and a family-like chemistry rather than adopting American rap tropes wholesale. The group’s three members-KOO, YOSI, and 200-each bring distinct roles to the table, and their second EP, home (February 6, 2026), marked their first comeback after roughly ten months.
This profile covers SIKKOO’s formation, agency history, member biographies, discography, and current activities in 2026. Where sources disagree or information is not publicly available, that is stated clearly.

Who Is SIKKOO?
SIKKOO is a three-member co-ed hip-hop group under AOMG. The lineup consists of KOO (Koo Min-jae), YOSI (Hwang Jae-hyun), and 200 (Bae Hye-jin). Before signing with AOMG, the members operated independently under SIKKOO Entertainment, a label founded by KOO, and released compilation-style projects and group songs without being an officially debuted group.
The group’s breakout moment came in 2024 with the Korean remix of Japanese rapper Yuki Chiba’s viral track “TEAM TOMODACHI.” The remix music video surpassed 10 million views on YouTube, bringing mainstream attention to the members before their formal debut. In April 2025, SIKKOO signed an exclusive contract with AOMG and became the first act of the label’s “AOMG 2.0” rebranding project.
SIKKOO’s identity is built on a family-like dynamic-the name itself signals closeness and shared experience-and a musical approach that blends rap, vocal performance, and production duties across all three members. They are not a traditional idol group; they are rapper-vocalists who write, produce, and plan their own releases.
Group History
Formation and Pre-Debut
SIKKOO began as an independent collective under SIKKOO Entertainment, founded by Koo Min-jae. At that stage, the members were not presented as a formal group but functioned like a label roster, releasing compilations and group tracks. The original lineup was a quartet, including a member named SIVAA. SIVAA withdrew from the group on March 10, 2025, and the group reorganized into a three-member system.
YOSI and KOO connected after KOO heard a song YOSI had posted on SoundCloud and reached out to collaborate. The group name was settled upon because the members felt a family-like atmosphere when eating together; YOSI proposed “SIKKOO,” and KOO wanted a Korean name that included his surname, “Koo”.
Official Debut with AOMG
SIKKOO joined AOMG on April 7, 2025, and released a “family relationship certificate” concept image to announce the signing. Their debut EP, GAN (간), arrived on April 29, 2025, alongside a debut showcase at Ilji Art Hall in Gangnam, Seoul. The EP’s title track, “BANGATGAN (방앗간),” presented a bubbly, wordplay-driven hip-hop sound that aligned with the group’s “domestic hip-hop” concept.
The debut was positioned as the opening move of AOMG 2.0, a broader rebranding initiative for the label. SIKKOO performed at KCON Japan 2025 on May 11, 2025, expanding their exposure to an international audience early in their career.
Breakthrough and home Era
The group’s second EP, home, was released on February 6, 2026, approximately ten months after GAN. The EP contained seven tracks, including double title songs “nosho” and “kinda Guilty,” plus solo tracks for each member: “bad trip” by KOO, “demons” by 200, and “AI LOVE” by YOSI. A release party was held on February 7, 2026, at Love Love Love in Seongdong-gu, Seoul, where the group premiered live stages for the new songs.
The lead single “nosho” performed well on streaming platforms, reaching No. 3 on Spotify’s Daily Viral Songs chart in Korea as of February 23, 2026. The EP was noted for broadening SIKKOO’s sonic range beyond hip-hop into melodic and genre-blending territory.
Recent Activities (2026)
In 2026, SIKKOO has been active in both group and solo capacities. 200 competed in Mnet’s Show Me the Money 12, finishing her run in February 2026 and earning recognition for her individual musical identity. The group continues to promote home and has maintained an official presence on Instagram, TikTok, and YouTube.
Agency and Management
SIKKOO is signed to AOMG, a major Korean hip-hop and R&B label. The group joined AOMG in April 2025 after operating independently under SIKKOO Entertainment, the label founded by KOO. AOMG describes SIKKOO as a “multiplayer-type artist group” capable of crossing genres and handling production, songwriting, and planning.
There is no publicly available information about the specific terms of SIKKOO’s contract with AOMG, including contract duration or renewal clauses. SIKKOO Entertainment appears to have been the group’s previous agency or internal label, but its current operational status is not publicly detailed.

Notable Songs
- “BANGATGAN (방앗간)” – The debut title track from GAN, built around Korean wordplay and a playful hip-hop hook. It established SIKKOO’s “domestic hip-hop” identity.
- “nosho” – A double title track from home that reached No. 3 on Spotify’s Daily Viral Songs chart in Korea. It marked a melodic, groovy shift in the group’s sound.
- “kinda Guilty” – The second title track from home, described as an homage to Dynamic Duo’s “Guilty” and a showcase for KOO’s raw rap style.
- “TEAM TOMODACHI (KR Remix)” – The pre-debut viral track that brought SIKKOO mainstream attention, with over 10 million YouTube views before their official debut.
Music Style and Artistic Evolution
SIKKOO’s music is rooted in hip-hop, but the group actively avoids a single rigid template. Their debut EP, GAN, leaned into Korean linguistic humor and a “bubbly” hip-hop energy, with tracks built around wordplay and everyday concepts. The title “BANGATGAN” (방앗간) refers to a mill or workshop, and the group used such domestic imagery to ground their sound in Korean culture rather than mimicking Western rap tropes.
By the time of home, SIKKOO had broadened their palette. The EP incorporated melodic layers, baile funk influences, and solo tracks that allowed each member to display a distinct flow and message. YOSI’s production role expanded, and 200’s vocal color became a more prominent part of the group’s identity. The double title tracks “nosho” and “kinda Guilty” show two sides of the group: one youthful and hook-driven, the other stripped-back and rap-focused.
All three members participate in planning and producing their releases, which is central to SIKKOO’s identity as a “multiplayer artist” group rather than a standard performance-based idol unit.
