Jiyu

Jiyu (지유), born Seo Ji-yu (서지유) on May 14, 2006, is the leader of KiiiKiii under Starship Entertainment. She debuted at 19 as the youngest leader of any Starship girl group, which immediately framed her as more than a centerpiece visual. She was the member trusted to carry the group's internal rhythm.

That role became visible fast. KiiiKiii launched its official channels in February 2025, dropped Uncut Gem on March 24, and claimed a first music-show win for I Do Me on Show! Music Core less than two weeks later. Jiyu led that sprint while handling vocal, rap, and performance duties inside a team that had to establish its identity immediately in the post-IVE spotlight.

Her page makes the most sense when read through that pressure. Jiyu is not being sold as a nostalgic trainee-story figure. She is the face of Starship's next-cycle girl-group bet, now moving from the breakout of Uncut Gem into the 2026 Delulu Pack era with KiiiKiii's official group platform functioning as her primary public channel set.
