CIX

CIX has disbanded.

CIX is short for "Complete in X." The name is introduced as meaning that the group becomes complete only when all of its members, each an unknown "X," come together. In Korean, it is read as "ssi-ai-ekseu." The meaning of the name also connects to the fandom's name.

CIX debuted on July 23, 2019, with "Movie Star." The song was the title track of the first mini album, HELLO Chapter 1. Hello, Stranger. That album opened the group's HELLO series storyline. The title track opened the door to the group's early concept and storyline.

At the end of its activities, CIX belonged to C9 Entertainment. The group's albums, concerts and overseas activities were all carried out through this agency. The members' current agencies and activities may differ, so please check each member's own official channels.

CIX debuted in 2019 and wrapped up its group activities in April 2026. The agency officially announced the end of the group's activities on April 29, 2026. Over about seven years, CIX shared several album series and activities in Korea and Japan with its fans.

The HELLO series is a sequence of CIX's early albums that began with the 2019 debut release. Title tracks such as "Movie Star," "Numb," "Jungle" and "Cinema" belong to this series. Listening to the albums in order feels like following a single connected story.

CIX began its OK series in 2021 with "WAVE" from the first full-length album, OK Prologue: Be OK. The group went on to promote "458" and "Save me, Kill me," and in 2025 it released the first album of its GO series. Each series showed a different mood.

CIX's fandom is called FIX. It is short for "Faith in X," a name introduced as connecting to the group's own name, "Complete in X." Even after the group's activities ended, fans continue to share their memories under this name.

Yes. CIX began its Japanese activities in 2020 with the Japanese single "Revival." The group later released more Japanese singles and the 2022 Japanese full-length album Pinky Swear. CIX met fans in both Korea and Japan. Both releases are a good way to hear the Japanese side of the group.

If you are new, start with the debut song "Movie Star," then listen to "Numb," "Jungle" and "Cinema" from the HELLO series in order. After that, try "WAVE" and "458" from the OK series to follow the path the group walked over about seven years.

Since CIX has ended its group activities, the most accurate way to follow the members is through each member's own official channels. Each member may have a different agency and field of work, so rely on official announcements. Please avoid spreading unconfirmed rumors.
