KiiiKiii

KiiiKiii is a five-member girl group from STARSHIP Entertainment, the agency's first new girl group since IVE. The group released its pre-debut song I DO ME in February 2025 and officially debuted on March 24 that year with its first EP, UNCUT GEM. In 2026, 404 (New Era) reached No. 1 on the Melon TOP100 and won on three music shows, and in August the group released its third EP, WhyKiiiKiii. Below are the members, releases, awards, and this year's schedule in order.

KiiiKiii at a Glance

The official spelling has three i's in each half. Searching for KiKi or Kiikii tends to mix in unrelated results, so typing KiiiKiii exactly gives cleaner results.

Profiles of the Five Members

Names and birthdays follow STARSHIP's official profile. Each name links to that member's page.

JIYU was already introduced as leader in coverage of the group's first M Countdown stage before the debut. Line distribution and positions change from song to song, so the stage videos on each member page are the quickest way to see who does what.

How the Debut Unfolded

KiiiKiii did not debut in one step.

1. February 16, 2025 — I DO ME music video released. The DEBUT SONG music video followed on February 23.
2. February 24 — I DO ME released as a digital single.
3. February 27 — First stage on Mnet's M Countdown.
4. March 24 — 1st EP UNCUT GEM released, with a debut fan showcase the same day at Blue Square Mastercard Hall. The music video for the B-side BTG premiered that day.
5. 13 days after the official debut — First terrestrial music show win with I DO ME on MBC's Show! Music Core.

This is why articles list the debut as either "February 2025" or "March 2025." February refers to the pre-debut song, while March 24 marks the official debut with the EP.

Discography and Music Pages

All releases are collected on KiiiKiii Music. Dates follow STARSHIP's official album list; the OST was released separately for the drama.

I DO ME appears on both its single and UNCUT GEM, and To Me From Me appears on both its single and Delulu Pack. That is why counting releases overstates the number of new songs. Go On was written for the MBC Friday-Saturday drama Perfect Crown and was the group's first drama OST.

Three Signature Songs and Their Results

I DO ME — The song that opened the group's career. After the Show! Music Core win, it took Music Video of the Year at MMA 2025 on December 20, 2025.

404 (New Era) — Title track of Delulu Pack, released in January 2026. It earned the comeback's first win on Show Champion, and with Show! Music Core and others it became a three-time music show winner. On the night of February 10, 16 days after release, it reached No. 1 on the Melon TOP100, the group's first Melon top spot, and it also topped Circle Chart's monthly digital and streaming charts. According to the agency, it stayed on the Billboard Global (excl. U.S.) chart for eight straight weeks and was the group's first entry on the Billboard Global 200. On July 15 (U.S. time), Billboard staff ranked it No. 1 on "The 25 Best K-Pop Songs of 2026 (So Far)"; that is an editorial pick, not a chart position.

Pop Off Pop Off — Title track of WhyKiiiKiii, released in August 2026. It features playful summer lyrics and shuffle dance choreography. The agency said the music video ranked No. 1 on YouTube's worldwide music video trending list the day after release. A report the next day listed it at No. 1 on the Bugs real-time chart and No. 29 on the Melon TOP100, with every track on the EP entering the Melon HOT100.

At the Seoul Music Awards, the group went from the rookie award to a main award the following year, winning two years in a row. At The Fact Music Awards, the rookie-category Next Leader prize turned into Artist of the Year within a year.
