TAG
ONE PACT · Main Rapper · Producer · RAPH4EL Solo Artist
Profile
TAG (Yeom Tae-gyun) is ONE PACT’s main rapper, songwriter and central music producer. Before joining ARMADA Entertainment, he debuted in Ciipher, and his experience as a rapper and creator became one of ONE PACT’s defining assets after the 2023 group launch.
The official Japanese fan-club profile credits TAG with work on almost every ONE PACT release, a pattern visible across the group’s contrasting records: PARADOXX’s heavy beats, the emotive fallIn’ mini album, the bright PINK CRUSH sound and 2026’s SANE and U so hot. He is also responsible for developing musical ideas and songwriting that complement each member’s voice.
His ONE PACK individual song someone else debuted in July 2025 with a special video. Separately, he began a solo recording project under the name RAPH4EL, releasing the EP 4/4 in March 2026 and subsequent singles including LOW BATTERY in April and W4STED in July. These are independent solo releases rather than ONE PACT member-track videos.
