The group was originally a six-member ensemble, but member Kim Garam departed in July 2022, leaving the current five-member lineup.
A Record-Breaking Rise LE SSERAFIM’s second EP, Antifragile, released in October 2022, became the group’s first release to sell over a million copies and made them the fastest K-pop girl group to debut on the US Billboard 200 at the time.

The group completed their conceptual trilogy with their fifth EP, Hot, in March 2025, which debuted at Number 9 on the Billboard 200 — making LE SSERAFIM the fastest K-pop girl group to score four top-10 entries on that chart.
