Le Sserafim (/lə ˈsɛrəfɪm/ lə SERR-ə-fim;[4] Korean: 르세라핌; stylized in all caps) is a South Korean girl group formed by Source Music, a sub-label of Hybe. The group consists of five members: Sakura Miyawaki, Kim Chaewon, Huh Yunjin, Kazuha, and Hong Eunchae. Le Sserafim was originally a six-member ensemble; Kim Garam departed from the group in July 2022. Le Sserafim debuted on May 2, 2022, with the extended play Fearless. It was followed in October with their second extended play, Antifragile, which 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. Both EPs' lead singles reached the top ten of South Korea's Circle Digital Chart and were certified platinum for streaming in South Korea and Japan. Le Sserafim's first studio album, Unforgiven (2023), marked their first number-one album on the Circle Album Chart and their first top-ten album on the Billboard 200. The album's singles "Unforgiven" and "Eve, Psyche & the Bluebeard's Wife" peaked at number two in South Korea and were certified gold for streaming in Japan. The group's first English single "Perfect Night" (2023) became their first number-one song on the Circle Digital Chart, topping the chart for six weeks. They achieved further success with the extended plays Easy, Crazy, and Hot, all of which debuted in the top ten on the Billboard 200, and the Easy Crazy Hot Tour (2025–2026), which became one of the highest-grossing K-pop tours of 2025.
