KPOP DISCOVER's CIX note
CIX is a boy group that C9 Entertainment sent out in July 2019, the name standing for Complete in X. The debut song Movie Star raised heavy visuals and tidy dance performance at the same time and made a vivid entrance for a fourth-generation act. Bae Jinyoung left at the end of his contract in 2024, and BX, Seunghun, Yonghee and Hyunsuk continued as a four-piece. They kept stacking up releases until the end of activity was announced with the expiry of the contracts at the end of April 2026.
Begin with Movie Star, Cinema, 458 and Save me, Kill me. Movie Star gives the entrance of polished dance pop, and Cinema turns to an open brightness. 458 lets the sheer intensity of the performing come through unfiltered and overwrites any impression that the visuals came first. Save me, Kill me from 2023 puts the lyrical side to the front, a late signature song that shows their strength in carrying feeling. Jungle with its dark storytelling, the bright pop of Wave and the Japanese release Pinky Swear make this a group that changed expression from release to release.
In 2022 the Japanese single Pinky Swear gave them a point of contact on both sides. As a four-piece in 2025 they left THUNDER FEVER and 'GO' Chapter 1 : GO Together, still cutting official releases after the change. The history closes with the end of activity in 2026, but the change only becomes visible across the whole seven-year run. Movie Star, then 458, then Save me, Kill me runs through the polish of the debut, the force of the performing and the depth of the lyrical years.
Editors' take Movie Star / 458 / Save me, Kill me — a C9 Entertainment four-piece from the debut through the performing to the lyrical years in three songs.
Trivia worth knowing
Taken in order, Movie Star, Cinema, 458 and Save me, Kill me separate polish, brightness, dance and lyricism.
All For You and Pinky Swear head the releases for Japan, which are worth following as a discography of their own.
From 2024 the group works as four members after Bae Jinyoung's departure, so Thunder and Wonder You read best apart from the earlier releases.
Art direction and colour design carry the music videos, so Movie Star, Jungle and Save me, Kill me leave a deeper mark when watched rather than only heard.
Beyond dance practice, official performance films from 1theKILLPO and Stone PERFORMANCE show how hard the stage side hits.
Setting EPEX and AB6IX alongside puts the C9 Entertainment lineage next to the boy groups that followed Wanna One.
Japan activity score
No. 126 of 241 groups with recorded activity in Japan (top 52%)
- 1Japanese releases
- 7Japan-related tracks
- 0Members from Japan

The denominator is the 241 groups, out of 564 covered by KPOP DISCOVER, whose raw score reaches at least one point. The score adds 10 points per Japanese-market release, 3 per Japan-related track, 12 per member from Japan, and 8 per official Japanese account. Japanese-market releases carry the most weight because they are the most direct evidence of activity; related tracks add track-level detail; members from Japan stand for Japanese-language communication and continuity; official accounts stand for a permanent point of contact. The weights are an editorial judgement, not a statistical optimisation, and the ranking tracks release volume in Japan closely.
